Reports earlier this year also linked Perumal with a multimillion-dollar scandal in Australian state soccer.
In September, Singaporean authorities arrested four alleged members of a global match-fixing syndicate under a special law allowing indefinite detention without charge.
A source said that businessman Dan Tan, whose full name is Tan Seet Eng, was one of those held in the crackdown.
In February, European police agency Europol said it had found evidence of match-fixing in top international soccer matches and it had uncovered an organized crime syndicate based in Asia that was behind the operation.
The biggest case of fixing in sport in Britain in recent years involved three Pakistan cricketers and a British agent who were jailed in 2011 for spot-fixing during a Test match against hosts England.
The four men were involved in pre-arranging no-balls during the internationals for shadowy South Asian betting rings.
