Dan Tan Seet Eng's name first cropped up in relation to match-fixing when Stern magazine alleged that he was the leader of the match-fixing cartel.
In an article in its July 28, 2011 issue, Tan was described as the financier of a syndicate which counted fellow Singaporean Wilson Raj Perumal as a member.
Stern also mentioned that a referee who officiated games under investigation by Fifa - Nigeria v Argentina and Bahrain v Togo - was on the payroll of the "Dan Tan cartel".
Tan, who lives in a Rivervale Crest condominium unit in Sengkang, was the director of Exclusive Sports from November 2010 to February last year.
Exclusive Sports was previously known as Football Four U - a company started by convicted match-fixer Wilson Raj.
Exclusive Sports had been in the spotlight for offering Finnish football club Tampere United 300,000 euros (S$481,000) in a deal struck late in 2010 that would allow football players from Asia, Africa and Latin America to be showcased there.
The club was expelled from the Finnish top flight last year following match-fixing allegations.
In El Salvador, Exclusive Sports was alleged to have organised a dodgy match between Costa Rica and El Salvador in October 2010.
Sources close to the investigations into match-fixing in Finnish football told TNP that Wilson Raj had named Tan during his interviews with Finnish police.
In January this year, Wilson Raj allegedly spilled the beans on Tan in a letter to The New Paper.
He claimed that he had done so because Tan had ratted him out to Finnish authorities by sending a whistle-blower to tip off Finnish police on his kelong operations in Rovaniemi, Finland.
Wilson Raj, 46, said: "Seeking police assistance is a violation of code number one in any criminal business.
"Dan Tan broke this code and stirred the hornet's nest."
Wilson Raj claimed that he was part of a global match-fixing syndicate headed by Tan, whom he and four other shareholders from Slovenia, Bulgaria, Croatia and Hungary reported to.
But the 46-year-old explained that his relationship with Tan soured when Tan allegedly tried to steal his business.
After serving 12 months of his two-year sentence for bribing players, entering Finland with a forged Singapore passport and obstructing the duties of government officials by trying to escape from custody, Wilson Raj was handed over to the Hungarian authorities under custody in March.
It is unclear if he has been charged for match-fixing or is assisting with investigations there.
