A man has been arrested after a sports car struck pedestrians on a residential street, leaving a 16-year-old girl dead and six others injured.
The red Audi A3 convertible is believed to have accidentally veered off the road at a corner and hit seven teenagers in Croydon, south London.
One girl died at the scene while six other injured teenagers were taken to a number of London hospitals.
Officers arrested a man aged in his 30s on suspicion of causing death by dangerous driving after he attended a south London police station on Sunday afternoon.
A Met Police spokesman said: "At this early stage it is believed the car was travelling at speed before it lost control at a corner and collided with the pedestrians.
"At this time there is nothing to suggest the car was driven deliberately at the group."
Police are appealing for any witnesses who saw the crash on Pixton Way at around 1.30am on Sunday to come forward.
The air ambulance, fire brigade and London Ambulance Service also attended the incident.
