A policeman filmed attacking a car has been put on "restricted duties" as Scotland Yard suggest the incident was a case of mistaken identity.

Dramatic footage, filmed by the driver and viewed thousands of times online, features a policeman smashing the windscreen after repeatedly telling the driver to "get out of the car", adding: "You're not allowed to drive it."

The Metropolitan Police said officers stopped the car thinking the driver was a man who was of interest to them but realised he was someone else. He was not arrested.
