A man who allegedly fled the scene of a crash in Singleton has been bitten by a police dog.
About 7.45pm on Saturday, police saw a suspicious blue Ford Falcon at the intersection of Mandurah Road and Singleton Beach Road.
It allegedly sped along Mandurah Road before crashing into a wire fence.
As police arrived they saw the front doors of the car open and believed the occupants had fled into bushland.
Officers took a rear passenger, a man in his 20s, into custody.
The area was cordoned off and police dog Utah was deployed.
He soon located a scent and tracked it for about 200m into an area with thick vegetation.
Utah found a man, in his 30s, hiding in the scrub.
The man allegedly resisted arrest which led to Utah biting him on the leg.
He was taken to Peel Health Campus for treatment.
During a search of the vehicle, police allegedly located two firearms and shotgun cartridges.
The investigation is ongoing and no charges have been laid at this time.
