POLICE are investigating two traffic crashes involving police vehicles that occurred last night.
The first incident occurred when police patrolling for a stolen vehicle around 8.50pm in an industrial area near Campbell Avenue in Wacol when the vehicle was sighted.

A male Constable, a male Senior Constable and two males in the other vehicle were all taken to hospital for treatment of non-life-threatening neck and back injuries.
The Forensic Crash Unit is investigating, and investigations into locating the suspect in the stolen vehicle are continuing.
