A 12-hour operation that started on Tuesday saw 14 individuals arrested on suspicion of being part of an organised group of match-fixers, the police and the Corrupt Practices Investigation Bureau said in a press release on Wednesday.
The operation was led by the Criminal Investigation Department (CID) and the Corrupt Practices Investigation Bureau (CPIB) with support from the Police Intelligence Department.
Officers raided various locations in different parts of Singapore to arrest the 12 men and two women.
Five of those arrested, including the suspected leader, are being further detained pending further investigations, the statement said.
Some were the subject of ongoing investigations in other jurisdictions for match fixing activities. The remaining nine persons will be released on police bail.
The police and CPIB added that it appreciated assistance rendered by the Interpol Global Anti-Match-fixing Taskforce and would continue to work with it and the global community to fight global match-fixing.
