Martin O'Donnell beat Thailand's Thanawat Tirapongpaiboon 4-2 at the 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 Commissionexternal-link 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.
