Police officers are hunting a gang of five or six youths who hurled a projectile at a car travelling along a 50mph dual carriageway and smashed its rear window.
The group of thugs were standing on Liff Terrace in Dundee's Dryburgh area overlooking the A90 Kingsway ring road when they struck.
They threw an unknown object at a passing white Mazda heading south-west, towards the area of a nearby BP petrol station and Subway shop.
