Referee Toshimitsu Yoshida reported to the Asian Football Confederation that he was offered money to rig a soccer match held last November in Thailand, according to media reports.
Several Thai newspapers said the Thai Football Association has begun an investigation into claims that match-fixers tried to rig the Thai F.A. Cup final last year.
According to Reuters news agency, Yoshida said he was offered money as the chief official to favor one of the two teams in Buriram United's 2-1 win over Army United, and later reported the offense to the AFC.
Interpol and the AFC will cohost a two-day conference to address match-fixing and corruption in soccer in Kuala Lumpur starting Wednesday.
Thai F.A. president and soccer world governing body FIFA member Worawi Makudi was quoted as saying in The Nation newspaper, "We have already received the report the Japanese referee sent. I'll discuss the incident with FIFA and AFC officials as well as with Interpol."
The Japan Football Association said it is aware of Yoshida's report to the AFC.
