has cost me my child, it's costing me everything. a drug epidemic is raging in townships across my country. nyaope is a highly addictive heroin—based narcotic, which sometimes contains hiv medication. it's often mixed with marijuana and smoked or injected. this drug is slowly eating away at south africa's first post—apartheid generation, and i want to find out why. my name is golden mtika, i'm a local crime reporter. i know the dangers of nyaope more than most. in the past six years, the drug has claimed the lives of two of my young nephews. i've come to the old neighbourhood

in search of answers. in the crowd, i spot one of my nephew's old friends. jesus came from a good home and was always immacutely dressed. i can't believe how far he has fallen. i would like to talk to him, but he is too far gone. seeing jesus has brought back memories. in the space of five years, i lost my twin nephews. both of my nephews were nyaope addicts. we tried our best to guide them to stop smoking this nyaope. at the end of the day, they ended up losing their lives. this is where my nephews

have been laid to rest. i'm sitting here right on top of this grave, and i've got my two nephews laying here, who died for nothing. life is so cheap. the loss of my nephews has had a devastating effect on me and my family, but we are not alone. most families have been affected by nyaope, you only have to turn the radio on and tv, newspapers, you see stories of this drug every day. this is power breakfast.

after what happened to my nephews, i am determined to helpjesus escape his addiction before he suffers the same fate. ifind him scavenging in an open sewer. like thousands of other addicts, he's desperate to buy his first fix of the day. he agrees to talk, but seems distracted. i need to finish rolling and start... and start lighting, and start smoking. in the morning, it's hell... you feel like you are literally

dying. your intestines are being cut by seven razor blade. at some point, you end up doing some very awful things. is there anything you wouldn't do if you didn't get a fix? i would do literally everything. if i have to hurt somebody or go stab somebody, i would do it. how are you feeling? i feel so relieved right ifeel so relieved right now. now i am relaxed. but feeding his addiction is a constant challenge. is it hard to get nyaope in the township? simple is staying. there is no

escape. no escape. it's hard seeing just how lowjesus has fallen. but in the nightmare world of nyaope, you can always sink lower. as i discovered, some ofjesus' friends are going to potentially deadly extremes to feed their addiction. in search of a bigger hit, they are not only injecting the drug but also share the needle. are you not scared of hiv? these guys are already taking one hell of a risk. but what i was about to see next was truly chilling. after injecting the nyaope, the addict draws his own blood back out into the syringe.

to make the hit go further, this mixture of blood and nyaope will then be injected by the others. what i am witnessing is sheer madness.

when i saw that, drawing blood from himself and injecting to the other one, it scared me most. my body was, like, you know, crumbling, he is going to inject that syringe. that is suicide, complete suicide for me. seeing jesus' friends risking their lives for nyaope has made me more determined than ever to try and save him. a few days later, a rehab centre has agreed to takejesus, and i go and try and find him again.

i find him at one of his regular spots, but it's not looking good — he's already smoking. i wonder if he will still feel the same about going into rehab. do you think you will miss this? jesus says his goodbyes. his resolve is strong. but i need to get him to the centre before his cravings begin.

the tenth commandment rehab centre claims to have a success rate of over 70%. it runs a strict regime. jesus is looking tense. joseph is a former nyaope addict who's mentoring new arrivals.

joseph sitsjesus down and explains the centre rules. he looks scared, but it is too late to back out. jesus has been addicted to nyaope for almost a decade. he will be kept under lock and key until he is clean. this programme may be his last hope for redemption. they sing. the next day, i return to see howjesus is doing.

but despite the cravings, jesus still seems determined. it's time for me to leavejesus. now he must fight his demons alone. i hope he can find the strength to beat nyaope. if he can, there's a chance he can rebuild his life and connect with his family again. thousands of young south africans are in exactly the same situation as jesus. but who are the shadowy people responsible for flooding our townships with the drug?

through my underworld contacts, i have managed to find a nyaope trafficker who is willing to talk to me, but he is suspicious. i have heard he is a key supplier to thousands of local nyaope dealers. ok, the stuff we have here, how long will it last? how much do you get? one township, ten kilos. i can't imagine the misery this is causing. how does it make you feel, when you look at one of these people in the township who has lost hope in his life, just because he is smoking this stuff?

all right, so this is basically for the sake of money. nyaope has long been illegal in south africa, so how can dealers like these operate so openly? how do you deal with the cops? all right, you just have to bribe them. how much money do you give a cop? is it only the junior—level cops, or up to the higher end? he is selling nyaope, and he doesn't care. what he cares about is money. i have lost my two nephews

through this nyaope. i think, for me, the government needs to come in very strongly and arrest each and every person who is dealing in nyaope, because they are killing our society. i have managed to find a cop who is prepared to talk about corrupt officers, who are feeding off the drug trade. i am meeting him at a secret location. hello. hi, hi, hi, myfriend. i am already around this area. 0k. he sounds a bit nervous, but he has promised that he is coming. we have disguised his identity to protect him.

do you notice that nyaope is now very common in our streets, on almost every corner of our streets? yes, yes, most especially in our townships. there, there is a lot of nyaope. it is killing our country, our community, our children and our brothers. how frustrating is it to you? i am trying to combat crime and protect members of the community, but some of our members, they are taking bribes from those who supply nyaope. how could the corruption be stopped? to stop corruption, arrest those police officers who is involved in crime. this cop is taking a big risk talking to me. it's very dangerous to cover up that story. they can kill me and also my family. thank you for speaking to me, and be safe. you are welcome.

the most disappointing thing about these police officers getting bribes from the dealers is that they are giving them the freedom to operate in our townships freely, and making drugs accessible to our children very easily. i want to find outjust how widespread the problem of corruption within the police force has become. a nyaope street dealer has agreed to wear a secret camera, but it is very risky. the cop sees him just after changing shift, and they will drive around the township seeing each and every dealer to collect money from them. it doesn't take long for a cop to take a bribe. over the next four days, our cameras capture police officers repeatedly receiving bribes

from a known drug dealer. we have obscured their faces to protect his identity. this is pretty obvious. a police van pulls in, and a dealer of nyaope comes with the police and tell them business is not good, but i will give you a cold drink. and in south african terms, cold drink means i will give you bribe money. for the love of money, they just collect money and they leave these drug dealers to roam around in our streets, sell drugs freely. so, to me, this is not good. it is not good at all. not only to me, but to everyone else in our society. we put these allegations to the south african police service. in response, they said...

they highlighted recent high—profile arrest the drug dealers in the johannesburg area. it has been six months since i leftjesus in rehab. we have been supporting his treatment, and i've heard he's now clean of nyaope. hi, jesus. hi, man. you are looking clean, you are looking very clean. very neat. you are looking... just look at you, man. i can't believe this is you. you are looking great, man. how has it been at the rehab? the hardest part was my first three days and the first week. those pains, those sleepless nights, you know. i'm finding it hard to put words to it, because even the thought of it is, like, i can't. do you think you would ever go back? no. to smoking, no.

i wouldn't go back to that. i am taking him home to meet his family, for the first time in years. i am a bit nervous, you know. what happens if your mum rejects you ? that's. .. that's going to hit me hard. home, sweet home. 0h, home, sweet home.

i'm just holding the tears to not fall, and looking like i'm going to cry for real, because i have been missing my mum.

i feel very proud aboutjesus. i hope that, you know, he will show up to them that he has really changed, because it all has to start with him. singing. jesus is back on the streets. this time, spreading the message to young addicts that the drug can be beaten. but, across south africa, dealers continue to push the drugs on the next generation. addicts are still hustling to get the money to pay for their next fix, and i continue to visit my nephews' grave, praying that other families can be safe

from the tragedy of nyaope. hello there. we've started this weekend on a fine note across many central, northern and eastern areas. quite a bit of sunshine around, but it's been gradually turning hazier through the course of saturday, like this picture behind me suggests across the south east of england. but further west, it's been a different story. we've had thicker cloud, outbreaks of rain. that's because low pressure‘s been slowly pushing in off the atlantic,

and this low pressure system is going to be a player into our weather as we head into next week. so, for sunday then, we're starting on a pretty similar note as how saturday started, with a little bit of mist and fog in some areas, which will clear quickly, and then there'll be plenty of dry and bright weather with some sunshine in central and eastern parts. but already we'll have cloud, with outbreaks of rain further west. showers and thunderstorms will develop though across scotland, northern england into the latter part of the day, but it will be quite a warm one again. 22 to maybe 26 or 27 across the south—east given the best of the sunshine here. but it's on in towards the latter part of the afternoon to the evening where some of these showers and thunderstorms could cause some problems and ,'ocally torrential falls of rain. hit—and—miss showers, but still, met office have issued a yellow warning for these. it's summer, these hit—and—miss showers and storms could affect the flood—sensitive areas across northern england. so, that's how sunday's looking. as we head on into monday, low pressure is firmly with us, mainly affecting northern and western parts initially, and then spreading further east as the week wears on.

so, it looks pretty unsettled, in fact, next week, particularly the first half of the week, where we'll see plenty of showers, maybe some thunderstorms, which could give rise to localised flooding in places. so our bands of showers and rain on monday, affecting eastern parts of england, scotland and also for northern ireland. breezy conditions in the south—west. however, there will be some sunshine around, too, it will not be a complete wash—out. temperatures nearly 19 or 20 in the north, and 23 to 2a degrees in the south—east. low pressure with us again on tuesday. weather fronts out towards our shores, causing some torrential downpours in places. the focus of them on tuesday across scotland, northern ireland and around some irish sea coasts. the best of any drier weather will be the sheltered east, where we could hold onto sunny spells through the day. temperatures to 22 maybe 23 degrees for most, a few degrees down from what we're expecting for the weekend and on into monday.

for wednesday, low pressure still with us, very unsettled, the northern half of the country with downpours, as you can see here. some could cause localised flooding and even affect flood sensitive areas across northern england. the best of the brightness again across the south and east of the uk. it's a similar story on into thursday. low pressure will be pushing out into the north sea, so these showers affecting scotland and we should be seeing some more sunshine around for northern ireland, for wales, central and southern england and perhaps a little warmer, 2a degrees in london. high pressure building in for the week to start the weekend, however as we move through the weekend, this big area of low pressure will move in off the atlantic. closely packed isobars and it will actually turn quite windy, too. one thing it'll be doing is digging up some warm air from the near continent. so it won't be colder despite it turning a lot more unsettled. so, into next weekend,

after that brief period of dry weather during the week, it will be unsettled. so there'll be some rain at times and it could turn quite windy, as you can see here. as far as temperatures remain average.

tonight at 10... police say several people may have been killed in a mass shooting in texas. it happened at a packed shopping mall in the city of el paso. at this time, we have ruled out multiple shooters. it's still active but, as of right now, we have one person in custody. desperate efforts to shore up a dam in danger of collapse in derbyshire. more residents nearby are told to leave their homes. talks to avert strike action at heathrow resume tomorrow. but more than 150 flights next week are already cancelled. and the first ashes test is delicately poised, despite early wickets for england against australia at edgbaston.
