behind me, and you can see still a couple of officers wearing white forensic suits jutting out from the promontory in the distance, it might be a bit far for you from home to watch that, and it gives you an indication of what we are seeing today, forensics officers, police officers, emergency vehicles, we have seen in inflatable boat being lodged into the water with a couple of police officers, sniffer dogs moving along the banks, and that gives you an idea of the scale of the operation and a variety of tools being used as part of the search of this area which is around 30 miles or 50 kilometres away from praia da luz were madeleine mccann went missing back in 2007. 0ur correspondent damien mcguinness, who is in berlin, told us more about the german police and prosecution leading this search. sol so i talked earlier today on the phone — so i talked earlier today on the phone to — so i talked earlier today on the phone to the german state prosecutor in the _ phone to the german state prosecutor in the city _ phone to the german state prosecutor in the city near where christian

the two teenagers, who local people here have said were on an electric bike or a scooter when they hit another vehicle. now, they were killed in that crash, but then exactly what happened after that, how things escalated is a little bit unclear. people have told us that they weren't getting enough information from the police at first, that they weren't quite sure what had happened, what the condition of those boys were, that a bit of a crowd gathered, that people wanted to pay their respects and that they were doing that peacefully when the police came in. some people have described heavy handed, and that's what escalated things. others have said that people came into this estate from other areas looking for trouble. but whatever, through the evening last night, things did escalate. there was quite serious disorder on particularly this part of the street and you can still see some of the damage, although there's been a big clear up operation here already today. there are still cars that have been burned out, cars with windows smashed. there are marks across the road where things were set on fire. the police had bricks and stones thrown at them and we know a number of officers were injured. the disorder went on for quite some time until the early

hours of the morning. and there's been an intense clear up here, people who live on this street trying to understand exactly what went on. many of them were afraid last night in their houses, not quite sure what would happen, how this would end, how dangerous things would be. we don't believe any local people were injured. certainly police officers, at least 12 officers were injured in the disorder last night. there have been appeals for calm because talking to people here today, they're concerned that there may well be a repeat of this later on this evening or in the coming days. there is a growing set of flowers around a lamp postjust over that hill, close to the scene of that crash. people have been coming to pay their respects to the two teenagers who lost their lives. so very much, the sense of people here is of grieving with those families, support for the families of those teenagers, but also concern about what happened here last night and the potential for possibly a repeat of it. some people have criticised the police, saying that they are not here enough in the mainstream and then turned up heavy handed last

night. other people who live here had a lot of sympathy for the police last night, who faced an absolute barrage of violence. so this is a story of disorder, disruption and damage, which is starting to be cleared up, but also potentially a story of disinformation and rumour where things escalated last night because of stuff that was spreading on social media, people not understanding exactly what had happened, not getting the correct information, and some people taking things to an extreme of disorder, which we saw last night. we've also seen police teams out this afternoon along this street, some of the neighbouring streets, gathering evidence, taking photographs, filming and talking to people, trying to get their accounts of what happened last night and who was behind the violence. earlier i spoke to canonjan gould, who's been the vicar in ely for seventeen years. she expressed her sadness about last night's events. 0bviously my initial thought is one of shock and despair, really, that this has happened,

a completely unnecessary incident. as i understand it, it's because people were spreading things on social media, blaming the police for the cause of the accident, which clearly it wasn't their fault, and things have obviouslyjust got out of hand. my concern now is that we try to keep calm as a community. it would be so easy, wouldn't it? people are really angry at what's happened last night, angry at the rioters, particularly. it would be so easy to retaliate if they know who those people are. but it is really important that nobody does that, that we stay calm and we let the police run their investigation properly. and, of course, through all of this, we must keep the families of those two youngsters in our thoughts and prayers at what is a very difficult time for them. but also the driver of the vehicle who was involved in the accident as well. that driver will be feeling very traumatised today. and, you know, without wanting to

criticise the youngsters who died, it is a reality that we have teenagers racing around this place on scooters and motorbikes really dangerously, really recklessly all of the time, often dressed in black, wearing balaclavas, racing up the wrong side of the road and expecting that cars will get out of their way. well, give us some context on that, and around what's been happening in ely, because there has been tension between the police and the community. i...i'm not sure i would agree with that. i think there's tension between the police and certain factions of the community who would tend to be those that might look for trouble, might be volatile. but actually, i would say that a lot of our community are really reassured by the presence of the police and recognise what a difficult task they have. the problem with youngsters being out of control is growing and growing and growing. it's fuelled by the drugs industry as well.

let's be honest about that. and the police are trying to maintain some kind of semblance of law and order. 0bviously, those that are disenfranchised, shall we say, are going to be antagonised by the police and their presence while others want the police there. and the police are treading this very fine line of trying to manage situations in such a way that it's not going to antagonise those that would be, while reassuring others. and... yes... it's a difficult situation. it certainly is. and it's a good distinction you make there, that it is some members of the community that may have run ins with the police. but have you been speaking to members of the community? what have they been saying to you about what's happened? so i was near the scene earlier today and talking to some of the residents who were out in theirfront gardens.

most people were feeling anxious. that was the overriding feeling, that they don't want this to happen again tonight. they feel afraid to go out after dark in case it does happen. others that i was speaking to were saying how angry they were that the police had been blamed for this and everybody should be giving the police their full support. that's what residents were saying to me. and this was obviously only in one street, because i've not had time to talk to many more people because i've been doing interviews all day. but i'm sure that they are not in isolation, those people in that street, i think that will be a general feeling across much of the community. a man who murdered a seven—year—old girl in 1992 has beenjailed for at least 29 years. david boyd, who's 55, lured nikki allan to a derelict building in sunderland where he hit her with a brick and repeatedly stabbed her. boyd was arrested at his home in 2018 and convicted after a three week trial earlier this month.

thejudge, mrsjustice lambert, handed down the sentence. i set the minimum term as one of 29 years subject to the consideration of the time you spent on remand, which is 366 days. i remind all of those listening that the minimum term is just that. a minimum term which cannot be reduced in any way after those 29 years have been served, there is no guarantee that you would be released. it's only if the parole board decides that you are fit to be released that you will be released, and even then you will be subject to licence and recall if you breach the terms of your licence. david boyd, stand up. for the murder of nikki allan on the 7th of october of 1992, the sentence of the court is one of life imprisonment. you will serve a term of 29 years, subject to the 366 days

which you have spent on remand, before consideration is given to your release by the parole board. that's the moment the sentence was handed down. 0ur correspondent rowan bridge has been outside newcastle crown court. if you look at some of the comments she made in her summing up there, she said that it was a crime that shocked and bewildered the community for 31 years, that nikki allan was loved, she left a hole in herfamily and a hole in the community in which she lived. it was a terrible crime that shocked a community, that went unsolved for three decades. nikki allan was a seven—year—old girl who was out on an evening, was lured by david boyd to a disused building, as we heard there, in sunderland by the dockside, where he attacked her, thejudge said, with a sexual motive. she said she believed that he either committed a sexual assault or intended to commit a sexual assault on nikki allan, who then fought back and screamed, and he then managed to get her into the building, where he then carried out what she described as a frenzied

attack on the seven—year—old girl using a brick and a knife, where he stabbed her multiple times and then he dragged her body to the basement of the building to try and hide it, to try and cover his tracks. in fact, her body was found the next day by two local residents, because such was the outpouring that people scattered around the area to try and find her and her body was found the next day. david boyd was initially interviewed as a witness to the case, not a suspect, and as you heard in that case, he generated a false alibi for himself, saying he had gone to get fish and chips, knowing full well that an innocent man had been arrested and stood trial for nikki allan's murder, a trial in which he was acquitted on the direction of the judge a year later. but it then took the campaign of nikki allan's mum, really, over those 30 years and the advances in dna technology, to be able to link david boyd to this crime, to his being found guilty by a jury here a couple of weeks ago and for the sentencing we have heard today. and as you say, it has taken a very

long time forjustice to be served, and of course very agonising for her parents. yes, that's right. i mean, we had some statements read out in court this morning from nikki allan's mum and dad, talking about the impact that the death of their daughter had on them, and notjust on them, notjust on the community, but on their children and grandchildren, even. this has been absolutely devastating to the allan family and their friends. nikki allan's dad david allan talked about how he couldn't walk past the building in sunderland where she had been attacked because it was a reminder of his daughter's death, even though he lived nearby. how he hadn't been able to go to funerals of people he knew because it reminded him of seeing his daughter's body in its coffin. her mum talked about how the impact was notjust on her, how david boyd had destroyed her life, had destroyed nikki allan's siblings' lives, and also her grandchildren's lives as well.

this has had a massive impact on the entire family. nikki allan's mum has had to campaign for 30 years, almost, it was 25 years before david boyd was arrested. she had to campaign over that time, which she said had taken a toll on her mental and physical health. she had been sectioned at one point because of mental health issues as a result of the stress that had been caused by her daughter's death. this has been absolutely devastating to everybody involved. around the world and across the uk, this is bbc news. cj has autism and after three heart attacks has disabilities which means he often has to use a wheelchair. he discovered photography as a teenager and hasn't looked back. i enjoy the photography

because i feel i hide behind my camera a bit because it's kind of like a comfort blanket, like a child would have. sort of my safety net. in his teens, he teamed up with professional photographer clive figes, who mentored him. they clicked and clive realised he had a gift. i learned to treat cj as a human being, a human being with gifts. i have got to treat him like a decent person, to show interest in him, because in every direction we take, the there's an awful lot of apathy. i spot things that people often overlook. you know, you wouldn't normally see. this relationship spanning 13 years has now seen cj recognised for his work by the royal photographic society. you're live with bbc news. the uk governement has said it would remove the right for some international students to bring

dependants into britain from january 202a. it's part of a plan to bring down overall migration levels. current rules allow postgraduate students studying courses lasting nine months or longer to bring partners and children to britain. they also allow international students to switch out of the student route into work routes before their studies have been completed, and that will also be removed in the new policy. the government said the number of dependants had jumped eightfold since 2019 to 136,000 people in 2022. for the year ending june 2022, net migration reached an all—time high of 504,000, and numbers could be even higher in some new numbers that will be published on thursday. live now tojonathan portes, professor of economics, king's college london. it's great to have you on the programme. especially because you have heavily studied the impact of migration in the uk, so what do you make of this announcement? could

there be a net benefit here? i make of this announcement? could there be a net benefit here?- there be a net benefit here? i think there be a net benefit here? i think the first thing _ there be a net benefit here? i think the first thing to _ there be a net benefit here? i think the first thing to say _ there be a net benefit here? i think the first thing to say is _ there be a net benefit here? i think the first thing to say is that - the first thing to say is that international students are a huge benefit to the uk, as the government's research and policy recognises. they come here, they pay money to our universities, they contribute to the success of our universities, and those of them who do stay on, which is a relatively small minority, in general are a benefit to the economy. so i don't think there should be any doubt that overall student migration, or students coming here, eitherfor the short term or long—term, are a good thing. that said, i think we shouldn't overstate the importance of this announcement. it is true that the number of dependents coming has rocketed in recent years, it has gone up by a lot. now, that in itself isn't a bad thing. dependents, students have to be able to support dependents, they can't claim benefits, they are not much of a drain on public services, and they

contribute to the economy by spending money. so on the whole look there an economic benefit to. but i think it's not unreasonable for the government to say the numbers have gone up very sharply in recent years, and it's not necessarily necessary for people who are coming here for only a relatively short time to bring theirfamily, their spouses, typically, with them. so i think this is not an unreasonable announcement. at we should keep, you know, we should focus on the sort of long—term objective, which is that the uk should continue to be an attractive place for people from abroad to come here to study. using these measures _ abroad to come here to study. using these measures make _ abroad to come here to study. using these measures make the _ abroad to come here to study. using these measures make the uk, - abroad to come here to study. using these measures make the uk, or enable the uk, the continued being an attractive place for people to study —— do you think that? what sort of impact do you think these rules will have on where people choose to go for higher education? it may mean we miss out on some students, particularly at masters level and particularly for countries where people often marry at a younger age and hence are more

likely to have dependents, in particular that's india or nigeria. and, you know, i don't think that's a good thing, it's unfortunate if we miss out on some of those students. 0n the other hand, the uk still has a pretty good offer, both in terms of the quality and number of university places here, and also in terms of our visa rules, and i think the important thing is that we still are keeping the work visa which enables them to come here, to stay on and try working here for a couple of years —— the graduate work visa. that is important, it would have been a very retrograde step of the government had cancelled that, and that will continue. so on the whole while i think this does make us somewhat less attractive, we still will remain a very competitive compared to most other countries. thank you for your analysis. let's bring you some breaking news now, these lines just coming into our newsroom. the arrest of evan

gershkovich has been extended by a moscow court, you will remember he is a reporterfor the moscow court, you will remember he is a reporter for the wall street journal, his arrest has been extended until the 30th of august. he was arrested in late march on espionage charges. journalists were not informed of this hearing in advance, and were not allowed inside court. this line hasjust advance, and were not allowed inside court. this line has just coming to us now, saying that his arrest has been extended for three months until the 30th of august. an bbc investigation has found vapes confiscated from school pupils in the uk contained high levels of lead and other metals. scientists are warning of serious health risks, with lab tests showing nickel levels nine times higher than what's considered safe. most of the vapes found on children

were illegal, and hadn't been registered with regulators. we can now speak to marcus saxton, chariman of the independent british vape trade association. thanks forjoining us. can we start with your reaction to these findings by the bbc that the babes did get into the hands of children and not only that, they contain some very dangerous components? —— that vapes got into the hands of children. thanks for having me today full service usually concern, as you outlined at the star, is important consumers understand these are illegal and not registered rates, there are many legitimate businesses that have existed for many years, where we would not find these products being sold, let alone the miners. so usually concerning and i think that introductory who gave is very important, to draw that distinction, and shows why consumers must go to reputable retail outlets. why does this happen? you seem to be suggesting the problem is that

people aren't buying vapes from official channels, but is that the only reason why this is happening? we have been existed, many of our members have, within the sector for ten years now, and ensuring protocols are in place to ensure that anyone who comes into our stores that looks under 25 will be age verified. unfortunately the last two years there has been a real explosion in demand for these products and as a result of that we find there is a supply coming to the uk as well as certain retailers who aren't reputable and are not following the right protocols, providing access to these products that as you say are illegal and also finding their way into the hands of minors, which is absolutely concerning and hence why consumers must buy from a reputable source and we were very closely with red letters in the uk to try to support them with what enforcement actions they can take in relation to these stores in more products they're selling who they are selling to.

what's the solution, then? from our it's lease what's the solution, then? from our it's please only _ what's the solution, then? from our it's please only purchase _ what's the solution, then? from our it's please only purchase from - what's the solution, then? from our it's please only purchase from a - it's please only purchase from a reputable retailer store, either a supermarket or a vape store. as far as we're concerned it's for the first who can really play a role, but we do understand they don't have the resources to manage these products that are making their way into the uk, that would be a real step for them to drive that enforcement at the border. thank you ve much enforcement at the border. thank you very much for— enforcement at the border. thank you very much forjoining _ enforcement at the border. thank you very much forjoining us _ enforcement at the border. thank you very much forjoining us from - enforcement at the border. thank you very much forjoining us from the - very much forjoining us from the the trade association. —— vape trade association. stay with us here on bbc news, i'll be back. a little dry weather to come, we recorded the highest temperature of the year so far and of this month in

cardiff. how does that compare with recent mays? it puts us firmly bottom of the league. normally may gives us much higher temperature so we can all agree there has been no heatwave and there will not be a heatwave and there will not be a heatwave any time soon either, because of the high pressure is in charge, winds are coming off the atlantic rather than france or spain, and that can often bring us some much warmer weather conditions. that said, in the may sunshine we will have a round of the next few days, it will feel pleasantly warm. the air is a bit cooler today, though, and a bit more cloud in the sky, so not quite as warm as yesterday but still pleasant if you are out and about in those sunny moments. northern scotland, will be quite different moves in, bringing patches of light rain. temperatures there are 1a or 15. at foremost, temperatures will be in the high teens to low 20s today. 0vernight tonight, there weak france will continue to pester the farmers of scotland. it won't be raining all the time, just a bit of dampness at

times. —— week weather front will continue to pester the far north of scotland. away from that, dry, 7—9. tomorrow, again, predominantly dry with plenty of sunshine for most. just across scotland this week weather front will move in, just across scotland this week weatherfront will move in, bringing a few spots of rain but nothing particularly significant. for most, temperatures still in the high teens, low 20s. 22, maybe 23 towards parts of the south west midlands, probably one of the warmest areas. but with all that sunshine around the may sun is strong, of course, that's what makes it feel warmer at this time of year. and we will have high levels of uv so if you're outside for any length of time it might be worth considering a bit of sun cream. a similar story for thursday, more dry weather, sunny spells and temperatures 23 or so in the warmest spot, which are likely to be taught south—east wales and may be towards the south—west midlands and south—west england. beyond that, through friday and the holiday weekend, a little dry

weather to come, it will feel warm in the may sunshine, temperatures climbing to the low 20s and could peak around 2a the warmest spot. goodbye for now.

this is bbc news, the headlines: cctv video emerges in cardiff, appearing to show a police van
