A teenager has died after the moped he was on was involved in a road traffic collision.

Jamie Flanagan, 18, was found with head injuries by police in Sidmouth Road at the junction of Milverton Road, Brondesbury, at 1.29pm on Monday August 10.

Police are unsure if he was the driver or a passenger on the moped.

The teenager was taken to the Royal Free Hospital where his condition worsened and he died on Wednesday August 12 at 9.40pm.

Police are appealing for the return of a moped and two crash helmets which were taken from the scene when he was in hospital.

The bike is described as a black Piaggio, Typhoon 125 with red/blue striped stickers and 'Martini Racing' logos.

The registration on the bike was P775 KOR and the full-faced crash helmets were black.

Det Insp Andy Rose, Alperton Traffic Garage, said: "Someone may have taken these items from the scene for a legitimate reason or for their own gain. It is important they are returned to us as soon as possible to assist the investigation into Jamie Flanagan's death.

"If you are in possession of, or know the whereabouts of, the items please contact police. You can be assured that we will speak to you in the strictest of confidence, however you may have come about this information."

A post mortem will take place at Northwick Park Hospital on Friday 14th August. An inquest will be opened and adjourned in due course.

Enquiries are on-going. No arrests have been made.

Anyone with any information is asked to call the Collision Investigation Unit on 020 8998 5319.
