The global network's suspected mastermind was among the 12 men and two women taken into custody in police raids lasting 12 hours across Singapore, ending early Tuesday.
"Among the 14 persons who have been arrested six persons are linked to ongoing European investigations or prosecutions such as those coming out of Italy, Germany, Finland and Hungary as examples," Interpol, the police body based in Lyon, France, said in a statement to The Associated Press. "All 14 are Singaporean nationals."
The arrests are of "extraordinary" significance and took down "the world's largest match-fixing operation based in Singapore," the secretary general of Interpol, Ronald K. Noble, said in an interview with Associated Press Television News.
"The Singaporeans have been criticized, unfairly I believe, for not being serious about fighting match-fixing," Noble said on a visit to Ukraine. "In fact, they never received the evidence of match-fixing that would have allowed them to either prosecute in their own country or extradite individuals. So what the Singaporeans did was they conducted their own investigation, working with Interpol, co-operating with (Interpol) member countries, from Italy, Hungary, Germany, Finland, et cetera. And they made their own investigations, targeted people for arrest who were engaged in match-fixing and made the arrests.
"Making an investigation that results in the arrest of the head and other members of one of the largest syndicates in the world won't end match-fixing, but it's a significant step," Noble said.
He later added: "What's significant is that the investigation in Singapore didn't just focus on the cases we already knew about originating out of Europe but also additional cases."
In Italy, the prosecutor leading an inquiry into international match-fixing said he would like to question the suspected ringleader.
"It's big news," Cremona prosecutor Roberto Di Martino told the AP. "It shows that our inquiry means something on an international level.
"Now we need to explore the diplomatic channels to see what we can do," Di Martino added. "I'm not sure if our treaties permit (extradition). Plus, these arrests appear to also be linked to their (Singapore's) own investigation. Others have been arrested, too, including women, that don't appear to have anything to do with our inquiry. I think there are some elements from our inquiry involved, and some from theirs."
A high-level police official told the AP that those arrested include Tan Seet Eng, widely known as Dan Tan. The official spoke on condition of anonymity because he was not authorized to discuss the detention publicly. Prosecutors in Italy have accused Tan of co-ordinating a global crime syndicate that made millions of dollars betting on rigged Italian matches and other games across the world.
"He's the leader, the general director of the ring," Di Martino said, adding that his office sent an international request for Tan's arrest "three or four months ago."
Earlier this year, Europol, the European Union police liaison agency, said it reviewed 680 suspicious recent cases of match-fixing, including some World Cup games.
FIFA also hailed the arrests.
"We welcome all actions taken by law enforcement bodies to bring the perpetrators of match manipulation to justice," FIFA said in a statement.
Di Martino has heard nothing from Interpol or anyone else over the arrests.
"I've had no official communication," he said. "Nobody told me officially that Tan Seet Eng was arrested. But that's evident from what is written in the Interpol statement."
The Singapore authorities did not formally name any of the people taken into custody, but said the "suspected leader" and several others wanted in other jurisdictions for suspected match-fixing were among those in custody.
Italian prosecutors investigating dozens of league and cup games they say were fixed had followed a trail back to Tan in Singapore. In court documents which laid out their findings, prosecutors alleged that Tan is the boss of a crime syndicate that allegedly made millions betting on rigged Italian games from 2008 to late 2011, through bribing players, referees and club officials.
Italian authorities issued an arrest warrant for Tan and listed him as their No. 1 suspect, but have been unable to take him into custody.
Still, at least 50 people have been arrested in Italy for match-fixing since mid-2011, with matches under investigation by prosecutors in Cremona, Bari and Naples. Point penalties have been handed out by the Italian football federation for three straight years, with four Serie A clubs penalized last season.
The Singapore police statement said the suspects are being investigated for match-fixing offences under Singapore's Prevention of Corruption Act and for involvement in organized crime.
The detainees are being held under a law that potentially allows Singapore's government to hold suspects without trial for up to 12 months, a detention period that can be extended. Introduced in 1955, that law has been used against suspected drug traffickers, illegal money-lenders and criminal gang members, especially in cases involving insufficient evidence for prosecution.
