Helicopter footage of officers wading into icy waters to rescue a man who had driven a suspected stolen car into a reservoir has been released by police.

The man was helped from the vehicle which had been driven into Carr Mill reservoir in St Helens on Monday evening.

Five officers were filmed rescuing him from the slowly sinking vehicle.

The man, who was found to be uninjured when taken to hospital, was detained on suspicion of a number of offences, including unauthorised taking of a motor vehicle.
