The Football Association of Singapore (FAS) has said that three Lebanese match officials have been withdrawn from refereeing an AFC Cup match.
Ali Sabbagh and assistant referees Ali Eid and Abdallah Taleb are to assist the Singapore's Corrupt Practices Investigation Bureau (CPIB) with its enquiries.
The FAS confirmed replacement officials have been appointed to take charge of the AFC Cup match between Tampines Rovers and East Bengal of India in their absence.
"Singapore and FAS have a zero-tolerance policy when it comes to matchfixing and football corruption," the FAS said in a statement released shortly before the match was due to kick-off.
"We take a serious view of allegations pertaining to matchfixing and football corruption activities and the authorities and FAS will spare no effort in minimising the possibility of such activities taking place within the local football scene."
In February, an investigation by Europol uncovered allegations of match-fixing in around 380 games across Europe and found that a further 300 games played outside the continent were questionable.
"We adopt a zero tolerance approach towards corruption, and matchfixing of any form is not condoned in Singapore," the CPIB said in an email to Reuters.
