Lie detector tests working in Singapore

The tiny Asian state has been one of the centres of match-fixing in football and Singapore FA general secretary Winston Lee said the introduction of polygraph tests had produced excellent results.

Lee, speaking at the Leaders in Football conference at Stamford Bridge, said: "It is now compulsory for all players to go through polygraph tests.

"They have to sign a form agreeing to the polygraph tests, and we can have a random test.

"Match-fixing is a cancer in football and it's everywhere, it's not just confined to Asia.

"We have taken a very strong stand against match-fixing and we are quite happy that it is working.

"It is also mandatory for players to report approaches by suspicious bodies.

"Recently some foreigners flew into the country and offered a large sum of money to a goalkeeper, and he reported this to our FA and we had these people arrested and they are now in jail in Singapore."

Wilson Raj Perumal, named by FIFA as among the world's most prolific match-fixers, came from Singapore.

Four men, including a former Malaysian footballer and a current Malaysian referee were arrested in Singapore in May on match-fixing charges.

International players' union FIFPro has said it is against players being forced to take lie detector tests after it was introduced by Bulgarian side Lokomotiv Plovdiv last month.

FIFPro lawyer Wil van Megen said: "Many scientists have criticised the use of the lie detector."
