The driver of a Bentley involved in a collision that left another driver in a critical condition may have been involved in a race, police have said.
Police were called at 10.40pm on Monday to reports of an accident involving a Bentley Continental and a Vauxhall Corsa on the A4 in Hounslow, west London.
The London ambulance service and London’s air ambulance attended the scene and the 42-year-old driver of the Vauxhall was taken to a hospital in central London where he remains in a critical condition.
It is thought that before the collision the driver of the Bentley may have been racing a third vehicle. The Vauxhall is not thought to have been involved.
The 30-year-old driver of the Bentley was taken to a hospital in west London and later discharged. He has been arrested on suspicion of causing serious injury by dangerous driving and has been taken to a west London police station.
The Metropolitan police said they were appealing for witnesses. Officers are keen to speak with the driver of the third car, or witnesses to the moments leading up to the collision.
Anyone with information is asked to call 020 8543 5157 or contact police via 101.
