A teenage girl is in a critical condition after a car being chased by police crashed into a lamppost.
The Met has launched an investigation into the collision, which happened in the early hours of Sunday morning in south London and left five women in hospital.
At around 4.25am, officers indicated for the car to stop near Streatham Common, but when it failed a pursuit was initiated until the car crashed into a lamppost on Greyhound Lane.
London Ambulance Service and London Fire Brigade crews attended the scene, and five women in the vehicle were taken to hospital.
Three are still being treated in hospital, including a 19-year-old who remains in a serious condition.
The other two have been discharged, and are being held under arrest in police custody.
Two of the women in hospital have also been arrested in connection with the incident, police have said.
Greyhound Lane was closed on Sunday as officers from the Met's Serious Collision Investigation Unit made inquiries.
The Directorate of Professional Standards has been informed, and the incident has been referred to the Independent Office for Police Conduct.
Officers have urged any witnesses to contact them on 020 8285 1574.
