THREE boys have been arrested after rocks they allegedly hurled from a bridge onto a New South Wales freeway smashed the windscreens of two trucks last week.
The boys allegedly threw the rocks from a bridge onto the F6 at Berkeley.
Police say they were called to the freeway at the Mullet Creek Bridge on April 12 following several calls about rocks being thrown at passing traffic.
One driver had narrowly avoided a serious crash after his truck ran off the road when it was smashed by a rock about 1.45pm.
Officers say they were talking to two truck drivers, when they saw rocks being thrown at passing traffic.
Police from general duties, trail bike police and Highway Patrol were called to the scene and three boys aged 9, 12, and 14 were arrested.
They were taken to Lake Illawarra Police Station where the older boys, aged 12 and 14, have each been charged with two counts of throwing rocks at a motor vehicle.
The boys were granted bail to appear in Port Kembla Children's Court on May 13.
Meanwhile the nine-year-old boy was released without charge.
