A CAR which side-swiped a vehicle in a near head-on collision on Tonkin Highway was being chased by police moments before the incident.

Police allege that early Friday afternoon, officers attempted to stop a Volkswagen Golf as it left an address in Maddington.

The vehicle failed to stop then continued driving along Tonkin Highway.

Police said a short time later the car allegedly travelled on the wrong side of the road, where it collided with another vehicle.

Both occupants of the vehicle then ran from police, but were apprehended a short distance away.

St John Ambulance said it transported two patients, a man and a woman aged in their late 40s and early 50s, from one of the vehicles that was hit to Armadale Hospital for treatment.

It is understood the driver managed to avoid a head-on collision but the vehicle was clipped by the car travelling on the wrong side of the road, forcing it into a spin and then causing it to crash into a tree.
