The Asian Football Confederation has banned two referees from Thailand for life for match-fixing.
The AFC disciplinary committee said on Friday that following a two-day meeting, Thanom Borikut and Chaiya Mahapab were found guilty of influencing the results of four matches each in a "manner contrary to sporting ethics."
It said the violations by Thanom related to four matches in 2013 and 2014, while Chaiya's ban was for four matches in 2012, 2013 and 2014.
The AFC said "in order to not prejudice other open investigations," the matches involved would not be disclosed.
The two officials are banned from all football-related activities for life, and the AFC said it asked FIFA to extend the bans on a worldwide basis.
