Three men have been arrested after police were led on a car chase in Waddon this morning.
At around 11.10am, police tried to speak to three men in a vehicle parked in Coldharbour Road.
Police said one man came out of the vehicle and spoke to officers whilst the other two remained in the vehicle, locking the doors.
The vehicle then apparently drove off from police and then crashed into an unmarked police car.
Police said two men then left the vehicle and one of them was detained by a member of the public.
A police spokeswoman said: "The man detained by the member of the public sustained a minor head injury and has been taken to a south London hospital.
"All three men have been arrested on suspicion of traffic offences.
"Two men are currently in custody in a south London police station."
