This was the dramatic scene after a BMW M3 was wrecked in a late night horror crash in south London.

The blue coupe was left wrapped around a lamppost with its roof sawn off and its chassis destroyed after the smash on Tuesday night.

The crash left a 19-year-old woman who was in the passenger seat seriously injured in hospital. The driver, a 28-year-old man, was also taken to hospital and treated for minor injuries. He has not been arrested.

Police said a Mercedes was being driven at speed close to the BMW when it crashed into a lamppost but failed to stop at the scene in Trinity Road.

Detectives are now hunting the driver of that car, possibly an AMG model, although it is not clear whether it was directly involved in the collision.

Shocking pictures of the aftermath show police officers inspecting the wrecked BMW, which has a rear tyre bent sideways, half a door ripped off and the windscreen smashed to pieces.

The roof can be seen lying on the grass a few yards from the rest of the car after being sawn off, while trees have been ripped out of the ground and cracked in two.

Detectives from the Roads and Transport Policing Command are appealing for information and witnesses which could help their investigation. The crash took place at around 10.25pm.

Anyone with information that may assist the investigation should call detectives from the Collision Investigation Unit at Merton on 020 8543 5157 or via 101.
