A man is assisting police with their inquiries after a sawn-off rifle was allegedly found in his car in Newcastle West early Wednesday morning.
Officers pulled over a Ford Falcon for a Random Breath Test on Cooper Street at about 1.30am.
However, they became suspicious when the three people inside started moving around as they approached.
A search of the car uncovered the gun as well as a hunting knife and a pocket knife.
The driver, a 27-year-old man from Charlestown has been arrested - the other two occupants have been released pending further inquires.
