The Singapore Police Force is helping its European counterparts to bust a global match-fixing syndicate.
It said on Tuesday night: "The authorities in Singapore are assisting the European authorities in their investigations into an international match-fixing syndicate that purportedly involves Singaporeans.
"Singapore takes a strong stance against match-fixing and is committed to working with international enforcement agencies to bring down transnational criminal syndicates, including those that involve the acts of Singaporeans overseas, and protect the integrity of the sport."
On Monday, the European anti-crime agency Europol identified about 680 suspicious matches, including qualifying games for the World Cup and European Championship, and two Champions League fixtures, as well as games in various top European leagues.
It said that 150 of these cases were linked to Singapore.
