Police are seeking witnesses after someone threw a rock through a van window at Moss Vale on Sunday.
About 3am on Sunday, a Toyota Tarago van was approaching the Lackey Rd overpass on Argyle St when a rock was thrown at the van, from the bridge.
The rock smashed through the window on the sliding door directly behind the driver, and landed inside the vehicle.
The 39-year-old male driver continued home and called police. He was uninjured.
Officers from Goulburn Local Area Command are investigating the incident and are appealing for anyone who may be able to assist with information to come forward.
