Trailing Singapore's 'football match-fixing boss'

European investigators say Singapore has become a centre for the illegal fixing of football match results around the world.

According to the Italian police, one of match-fixing's key figures continues to live freely in Singapore.

But much to the frustration of European investigators, Dan Tan Seet Eng remains a free man and the Singaporean police seemingly powerless to act.

The authorities know where he is and have even invited him in for a chat.
