SINGAPORE - Businessman Dan Tan Seet Eng, who is said to have rigged over 150 football matches in countries including Italy, Hungary, Finland and Nigeria, was freed from detention by the Court of Appeal on Wednesday (Nov 25).
The 51-year-old has been in prison since October 2013, after being detained under the Criminal Law (Temporary Provisions) Act, which allows for detention without trial.
On Wednesday, the Court of Appeal ruled that his detention was unlawful after his lawyers challenged his continued detention.
The Straits Times looks at five of the most notorious match-fixers in Singapore.
Dan Tan Seet Eng
Wilson Raj Perumal was jailed a year in 1995 for giving US$2,400 (S$3,234) to a football team captain to throw a match in September 1994. He then went on to fix bigger matches, all the way to the World Cup, and became Fifa's most wanted man.
In February 2011, the Singaporean was arrested in Finland and served one of a two-year sentence for fixing top-tier games there. He also decided to collaborate with the Finnish authorities, revealing a global network of match-fixers based in Singapore where he fingered Dan Tan as the boss of the operation.
In an interview with CNN last year, Wilson Raj said he earned "five to six million dollars" from influencing "80-100" matches in his two-decade run of match-fixing.
Having completed one year of his sentence, he was extradited to Hungary in 2012, where he is currently under house arrest and assisting match-fixing investigators.
The father of twins now lives in Budapest and has also co-written the book Kelong Kings: Confessions Of The World's Most Prolific Match-fixer.
