stephen chapman is leading the fight against slavery and labour exploitation in wales.rs there's been a 300% rise in reported trafficking and slavery cases across the uk. this has been low risk, high reward for the criminals. what we have now got to do is make it high risk for them and, and no reward. but traffickers fedak and feko took the risk. one of their victims was bought and sold into slavery in cardiff. i'm heading to the czech republic to find him. over an hour's drive from prague is the region of hradek kralove. this is where it all started. victims were found often on the streets of czech towns, in some were even homeless. they were the kind of people who no one go looking for when they disappeared to the uk. but they were all down on their luck and they fell for the same old lies, the promise of a better life in cardiff. i'm meeting the first of their victims to break his silence, he's a father in his forties. he's asked us not to identify him. translation: i was living in a boarding house but when my welfare benefits were cut i couldn't stay there anymore,
