A TEENAGE motorcyclist is in hospital with head injuries after a serious accident which witnesses say he was lucky to survive.

The collision took place at the junction of Northwood Road and Breakspear Road North (pictured) in Harefield at 7.10pm on Friday evening.

Police confirmed yesterday morning (Tuesday) that the teenager is in a stable condition and has no life-threatening injuries.

The London Ambulance Service reported that the boy was 18-years-old.

Residents living in the road heard the noise of the accident and rushed out to help the youngster.

One resident of Northwood Road who asked not to be named, said: "He was lucky to survive, he was thrown a long way off his bike, around 20 feet.

"His helmet had also come off and was lying in the road next to him.

"A heart surgeon at Harefield Hospital who lives nearby ran out with a stethoscope, but the paramedics were here so quickly.

"They were here working on him for around two hours, and that's when you know it is serious. The police were out here with measuring sticks, investigating the circumstances.

"Two people came up to me the next day and said they heard it was a fatal accident but I am so glad to know it wasn't."

The road was cordoned off until after 9.30pm on Friday night, and shards of headlamps and debris are still visible at the roadside.

The teenager was riding a Kawasaki motorcycle, and car he collided with was a black Vauxhall Corsa.

Detective Sergeant Chris Osborne of Alperton Traffic Police attended the scene.

He said: "He was going down Breakspear Road North away from Harefield, and a car was coming out of Northwood Road turning right and they collided.

"The driver stopped at the scene and is helping us with our enquiries and there have been no arrests."
