Police have been urged to protect footballers from bookmakers as the Malaysian Football Association (FAM) prepare to investigate claims of match-fixing in the country's league in a meeting on Thursday.
Local daily newspaper The Star reported that a match in the second tier of the Malaysian Premier League between Kuala Lumpur and Sime Darby was under suspicion. Banners with the message "Bookie detected" were seen at the game which finished 5-0 to Sime Darby.
The police are also due to attend the meeting, as are the Malaysian Anti-Corruption Commission.
FAM deputy president Tengku Abdullah Sultan Ahmad Shah told reporters: "We have to look into this allegation of match-fixing seriously. We will discuss it with the sports minister on Thursday.
"The police need to keep a close eye regarding the threats. The players must not get close to the bookies. Once you open up, you will have to face the consequences."
There is a long history of match-fixing issues involving players and referees in Malaysia. High-profile cases have occurred in Lebanon, China and South Korea in recent years. European anti-crime agency Europol also claimed that Singapore was at the centre of a rigging ring.
