A TEENAGER told a court how he saw a policeman clinging to the door of a car which was reversing at high speed.

Ryan Grundy said he heard a commotion outside his house and went to his bedroom window to see what was happening.

The 17-year-old told how he saw a car reversing at speed and heard someone shout "stop". One of the men was hanging on to the passenger and the other one was running alongside the driver's side.

Mr Grundy was giving evidence in a trial where Sgt David Holt was injured when a car he had stopped suddenly reversed at speed, flinging him into a car behind.

The driver, Kenneth Gregory, admitted driving off with the officer hanging on to the door, but said he did not know they were police officers and thought he was going to be robbed.

The teenage witness said he assumed that the men were police officers because he saw one of them show a warrant card to an ambulance driver.

The court heard earlier that the plain clothes officers had been driving an unmarked police car when they stopped Gregory and two passengers in Bradford Road, Great Lever.

Gregory was later arrested. The 59-year-old, of Ainsworth Road, Radcliffe, is on trial at Bolton Crown Court. He denies dangerous driving, attempting to cause grievous bodily harm to Sgt Holt, and assaulting PC Christopher Walker causing actual bodily harm, on June 15.
