A gang of suspected armed robbers rammed their car into police while trying to flee arrest in Liverpool.
Officers had pulled over three men in a black Renault Megane near Switch Island, Aintree, on Sunday evening when the car sped away.
When the car got stuck in traffic in Ormskirk Road it reversed into the police cars which had followed.
Three men, aged 31, 33 and 39, were arrested on suspicion of conspiracy to commit armed robbery.
One the suspects suffered minor injuries during the collision and was taken to hospital to be treated for his injuries.
