World Snooker investigates betting patterns at Paul Hunter Classic
World Snooker is investigating "unusual" betting patterns in a match between England's Martin O'Donnell and Thailand's Thanawat Tirapongpaiboon at the Paul Hunter Classic in Germany.
O'Donnell, who won the fourth-round tie 4-2, is not under investigation.
World Snooker (WPBSA) will liaise with the Gambling Commission to determine if further action is necessary.
O'Donnell will play Duane Jones in the fifth round of the tournament, which is part of World Snooker's Euro/Asia Tour.
Tirapongpaiboon was cleared of wrongdoing after the WPBSA investigated suspicious betting in two Shanghai Masters qualifying matches in 2013.
