Three teenagers have been convicted of killing a police officer during a desperate attempt to evade capture.
PC Andrew Harper was dragged for a mile behind their car, after he tried to stop the group towing away a quad bike, stolen from outside a house in west Berkshire.
The driver, Henry Long, 19, and his passengers Albert Bowers and Jessie Cole, both 18, had denied murder. Long earlier admitted manslaughter and his co-accused were found guilty of the same offence by a jury at the Old Bailey in central London.
