Frank Acheampong's Chinese Super League side Tianjin Teda are being investigated for match fixing after a suspicious 4-1 derby win over Tianjin Quanjian last week Saturday.

Acheampong scored twice in the space of two minutes to move out of the drop zone with five matches left to play.

The two team's involved in the clash will be the subject to a match fixing probe by Chinese football authorities.

''The Chinese Football Association has launched an investigation into the CSL game between Tianjin Teda and Tianjin Quanjian,' a statement read.

''A probe panel consisting of CFA's competition and legal departments, Committee for Ethics and Fair Play and a Disciplinary Commission will collect all available facts and evidence related to this game.

''Any violations of fair play would be severely dealt with according to the extant laws.''
