Yeah, there was a BBC documentary with him in it, and they actually demonstrate this. Various scammers are arrested and even sentenced, and then for some totally innocent reason a mistrial gets called, and it all has to go to trial again, and surprise surprise in the intervening time the police have managed to lose all of the evidence.
The only good thing about that whole case was that when they were arrested the scammers faces were broadcast all over national television in both India and the UK. Not that been shown in the UK will do everything, but I’m sure they don’t have a great time in India because the locals hate them. Oh and also when the police are showing off their scammers, for some reason they make them hold hands with the police. It’s really funny how unhappy they look about it.
