Singapore: Dan Tan was re-arrested this week because he was suspected of running a global soccer match-fixing syndicate and a danger to public safety, the Singapore government said on Saturday.
Tan, whose real name was Tan Seet Eng, was detained on Tuesday, a week after his release from jail was ordered by the Singapore Court of Appeal, which ruled he was not a risk to public safety.
The Ministry of Home Affairs released a statement saying the fresh detention order was for Tan's "involvement in global soccer match-fixing."
"The new detention order ... Expressly sets out the grounds which show the extent of (his) match-fixing activities from and within Singapore.
"The grounds set out the seriousness of Dan Tan's criminal activities over many years, their impact on public safety, peace and good order within Singapore, and the fact that he has intimidated witnesses to the extent that they continue to be unwilling to testify against him for fear of reprisal."
Singapore's detention laws are used in cases involving insufficient evidence for prosecution.
Hamidul Haq, one of Tan's lawyers, told the Associated Press he had not seen the detention order, and was unable to comment if his client will appeal.
Tan was previously jailed in October 2013 after Italian prosecutors accused him of coordinating a global crime syndicate that made millions of dollars betting on rigged Italian matches and other games around the world.
When the Singapore Court of Appeal ruled last week he was being held unlawfully and ordered his release, officials from international sports bodies were outraged.
Italian prosecutor Roberto Di Martino referred to Tan as the "general director of the ring" that fixed matches for more than 10 years.
He is also being tried in absentia by a Hungarian court for allegedly manipulating 32 games in Hungary, Italy, and Finland.
