## Match Fixing Incident

In the last league fixture, Bangkok Bank of Commerce lost 0-10 to Royal Thai Air Force in a match that widely believed to be fixed as Royal Thai Air Force won the league by a single goal differential. Investigation led by the Football Association of Thailand had the manager and one of his assistants suspended. Bangkok Bank of Commerce got expelled from the association, and later folded due to financial difficulties. There was no punishment to Royal Thai Air Force or its personnel, however.
