A HAMPSTEAD man has died after being seriously injured in a collision on the M4.

The 53-year-old victim was hurt last Tuesday when his motorbike hit the central reservation of the westbound section of the motorway in Brentford.

Police and paramedics were called to the incident at 9.40pm.

The victim was treated at the scene before being taken to a central London hospital where he died on Saturday evening.

Traffic officers are now investigating the case and have appealed to any witnesses who saw the collision to come forward.

Detective Sergeant Harry Wilkinson, who is leading the investigation, said: “I am grateful for a number of people who stopped at the scene to assist the emergency services that night. This stretch of motorway was fairly busy at that time and I would urge anyone who may have seen the motorcyclist in the moments leading up to the collision, or the collision itself, to contact Police.”

At this stage no other vehicles are believed to have been involved in the collision.

Police say they are awaiting the opening of the victim’s inquest before he can be named.

Anyone with information is asked to call the Road Death Investigation Unit at Hampton Traffic Garage’s witness appeal line on 020 8941 9011.
