Police in Exeter are investigating a dangerous driving incident in which a marked police car was rammed by another vehicle.
Officers believe the same blue Ford Ka may have also reversed into a light coloured Peugeot with an L-plate on the bonnet - and they're trying to trace the occupants who may be able to help their inquiries.
It happened in Holly Road, off Burnthouse Lane, at about 11.30am on Wednesday.
A 19 year old man has been arrested on suspicion of driving while disqualified, aggravated vehicle taking and failing to stop for police - he's been released on bail until February.
