A policeman is fighting for his life in hospital after he and a female colleague were smashed into by a Maserati sports car in Neasden in north west London.

The police officers - a man and a woman both in their 30s - were returning to their car on the A406 near the junction with Dog Lane in Brent Park after dealing with an unrelated matter when the car careered into them at around 3.40am on Sunday (17 December).

Met Police said the male officer is in" a critical condition". It described the state of his female as serious but stable after sustaining "a number of fractures".

A female passenger, who is in her 40s, in the white sports cars was injured in the crash and the car itself sustained serious damage and stopped at the scene.

The male driver, who is in his 50s, was arrested on suspicion of dangerous driving and for failing to provide a breath specimen. He has been taken to a north London police station where he remains in custody.

Brent MPS warned motorists to avoid the area before surrounding roads were opened later in the day. "Emergency services and police are dealing with a road traffic collision on A406 North Circular Road in which two police officers sustained injuries," read one tweet. "Road closures are in place, and we advise motorists to avoid the area and seek alternative routes."

Anyone who witnessed the collision or has information that may assist police should contact the Serious Collision Investigation Unit at Alperton on 020 8991 9555 or via Twitter @MetCC.
