What happened to the hundreds of football hooligans who rioted during the European Championships two years ago? The second programme in the series 'Kicking Off' tells the shocking story of the thugs of Euro 2000 and how they are still causing mayhem today. Many will remember the disturbing images of so-called fans running riot in the street. Their behaviour helped destroy England's chances of holding the World Cup in 2006. Many were arrested and later deported. But what happened to them when they came home? This nine month investigation, filmed undercover often in the middle of riots and running street battles, tracks their activities since Euro 2000. The programme shows how one hooligan group helped stir up the recent Oldham race riots and how another, the Cardiff City Soul Crew -one of the biggest and most notorious in Britain - has become involved with the club's high-profile owner, Sam Hammam. There is also startlingly frank testimony from a former far-right activist and Chelsea hooligan, - now in hiding after he turned informer, who was present at the Euro 2000 and involved in the Oldham riots - and the veteran undercover policeman who tried to combat hooliganism at home and abroad.
