A Ferrari driver has been arrested after seven teenagers were injured in a collision with his sports car.
A 17-year-old boy and a girl aged 16 remain in hospital after the incident in Battersea Park Road, south London, shortly before 10.30am on Monday. Their injuries are not believed to be serious, the Metropolitan Police said.
Five other pedestrians - four boys and a girl, all in their late teens - were treated for minor injuries but were later discharged from hospital.
The 35-year-old driver of the red Ferrari 458 stopped at the scene and has been arrested on suspicion of causing serious injury by dangerous driving. He remains in custody at a west London police station, Scotland Yard said.
Pictures taken at the scene showed the sports car on the road with a smashed windscreen.
Emergency services, including London's Air Ambulance, attended the incident and road closures were put in place.
Detectives from the Metropolitan Police have appealed for witnesses.
