Police are appealing for the driver of a vehicle which they think was transporting rocks around the Island on Friday to come forward.
It's believed a rock from it fell off and smashed through the driver's side window of a black Renault Megane.
The car was parked on Ramsey Road in Laxey, near to Minorca Crossroads, between 2pm and 4pm.
Anyone who can help is asked to contact Police Headquarters.
