A critically injured man taken to hospital by air ambulance remains unidentified by police who are appealing for anyone who may know him to come forward after a road traffic collision.

Officers were called to Langley Road shortly after 8pm on Saturday, December 29, after a pedestrian was found to have been in collision with a car.

The driver stopped at the scene and no arrests were made.

The injured man was airlifted to a hospital in east London in a ‘life-threatening condition’, but police have not been able to confirm his identity.

The man is believed to be around 40 years old and is described as stocky, with short brown hair and wearing a dark blue woolly cardigan, dark blue jeans, Doc Marten Airwair boots and two pairs of thick socks.

He was found with a train ticket from Abbey Wood to Woolwich Arsenal, purchased the same day.
