POLICE are calling on residents for help in catching the culprits who have thrown rocks and stones onto cars from a bridge in Headless Cross.

A woman driver suffered cuts to her hand after her windscreen was smashed in one of four attacks over the weekend.

On Monday evening, a Redditch man managed to avoid injury after a log was hurled in front of his car.

Inspector Gareth Prosser, of Redditch police, said: "The objects are being thrown onto the A448 dual carriageway between Redditch and Bromsgrove and there is the potential for a very serious collision."

He added: "Someone may have spotted someone throwing objects off the bridge and I would ask they contact us on 08457 444888."
