At about 10.10pm on Monday visitors to the area had called in to refuel at the Taree Service Centre, Taree South and were heading back out towards the highway when their car was struck twice by large rock/brick type objects.

The male and female occupants of the car were shaken and scared, reporting a "noise like you've never heard".

Two objects were thrown at the car with such force that the victims had no doubt that had the rocks hit a window they could have seriously injured a passenger.

The stretch of road where the incident occurred is just before the roundabout into the service centre and both victims noted the lack of lighting on the stretch, only serving to assist the rock throwers in their efforts.

They drove straight to Taree Police Station and reported the incident to the officer on duty, who took down their details and assessed the damage to the vehicle.

Police are continuing to investigate the incident and have since been to the site to search for evidence.

They ask anyone with information on the matter to contact Taree Police Station on 6552 0399, or Crime Stoppers on 1800 333 000.

If you've been a victim of rock throwing in the Manning the police want to hear about it as this is a serious offence and should be reported.
