A teenage joyrider who repeatedly drove into a police officer during a traffic stop will spend 29 months in a young offenders' institute.

Jamie Campin, 18, had been seen driving a red Nissan Micra erratically in Blyth Road, Hayes, on October 9 at about 11am. He refused to stop when instructed by two officers to pull over.

When Campin got stuck behind traffic, one of the officers, a 39-year-old constable based in Hillingdon, went over to the driver's side door to attempt to speak to him.

It was then that Campin reversed at him, trapping him between a lorry and a lamppost. He reversed again and the PC broke free, but not before Campin drove at him again and hit the post.

The officer managed to break the passenger window with his baton and shouted at Campin to stop, but the teenager ignored him and drove off towards Dawley Road.

More police arrived, and officers caught up with Campin a few minutes later in nearby Cromwell Road, where he had crashed into a telephone pole and damaged a parked van while trying to avoid capture.

It was later discovered the car was stolen and bearing false number plates.

The officer suffered cuts and bruising to his legs and arms.

Campin, of Hillingdon Road, Uxbridge, admitted attempted GBH to a police officer and aggravated vehicle taking, and was sentenced to 29 months and 13 months respectively, to run concurrently, at Isleworth Crown Court on Monday, February 3.

Detective Constable Laura Frost, who investigated the case but was not involved in the incident, said: "Campin showed an extreme level of violence towards the officer, and thankfully the injuries were not serious.

"A very dangerous individual has been brought to justice."
