Police are appealing for witnesses after a rock-throwing incident at Primbee on Saturday night.
About 9.30pm, a silver Commodore wagon was heading north on the Primbee Deviation.
The 39-year-old driver heard a loud bang as he passed the intersection of Lakeview Parade, but continued driving until he reached a car park on King Street, Warrawong.
At this time, the driver saw his rear window had been smashed.
He drove back to Primbee Deviation and allegedly saw four boys, described as being about 14 years old and wearing dark clothing, who ran from the area.
The driver returned home and contacted police. He was not hurt.
Police from Lake Illawarra Local Area Command attended the scene and patrolled the area, but could not find anyone.
Traffic and Highway Patrol Commander, Acting Assistant Commissioner Stuart Smith, said rock-throwing was a deplorable act.
‘‘This is an extremely dangerous and cowardly act,’’ Acting Assistant Commissioner Smith said.
‘‘Residents in the townships involved need to talk to their children about this kind of reckless behaviour to prevent it from happening again.
‘‘Throwing rocks at vehicles can not only cause them to crash, but also seriously injure the drivers or passengers.
‘‘It’s imperative that police find out who’s responsible for these incidents, and I encourage anyone with information to contact Crime Stoppers on 1800 333 000.’’
