Singapore - A businessman accused by Interpol of being "the leader of the world's most notorious match-fixing syndicate" was re-arrested by the Singapore police on Tuesday, nearly a week after he was released from two years of detention, local media reported.
Local newspaper The Straits Times reported that 51-year-old Dan Tan Seet Eng had been re-arrested by the police "for investigations into suspected involvement in criminal activities."
The police did not elaborate on what the criminal activities were.
Tan was detained from October 2013 until last Wednesday under the Criminal Law (Temporary Provisions) Act. The law allows the Minister of Home Affairs to order the detention without trial of suspected criminals. The detention order lasts up to a year, but can be renewed annually.
Singapore's appeals court ordered Tan's release on November 25 after finding that he posed no threat to public safety.
His release was criticised by former Interpol secretary-general Ronald Noble and former head of security for FIFA, Chris Eaton.
"Match-fixing is a corruption like cancer, dangerous whether it is visible or not," Noble told local newspaper TODAY last week upon Tan's release.
Tan was accused in 2011 of fixing matches in Italy's Serie A and Serie B. The Italian government issued an arrest warrant for him in December that year.
He was also named in May 2013 by Hungarian prosecutors for his alleged role in an international match-fixing conspiracy that involved numerous Hungarian and international matches.
