A police officer has been injured after he was dragged along the road by a car.
Officers had stopped a Honda car in the Mourne Park area of Newtownstewart shortly before 11pm on Tuesday night, when the driver suddenly sped off.
One of the officers was dragged along the road by the car, before being thrown off.
He sustained a number of cuts and bruises to his head and body, the PSNI said.
The Ambulance Service was called just before 11pm on Tuesday night.
One rapid response vehicle and one A&E crew attended the scene.
The policeman was treated by paramedics and following an assessment he was taken to hospital for further treatment.
Other officers on patrol in the area spotted the car a short time later in the Old Castle Road area and forced it to stop.
A 17-year-old male was arrested on suspicion of a series of motoring offences.
In March, a PSNI officer escaped serious injury after a hit-and-run incident near Dungannon.
He was struck by a silver Lexus while investigating reports of dangerous driving in The Bush area.
