Two men were arrested at Walkley Heights on Saturday afternoon after a car reversed into a patrol car.
Police received a report of two men acting suspicious at a house in Frances Avenue, Para Hills address about 3.40pm on Saturday 4 July.
A patrol attended and located two men with a silver Subaru station wagon. It will be alleged that when officers tried to approach the pair, one man tried to punch an officer and ran off. While an officer was reaching in to remove the car keys, the other man reversed the car, clipping the side of the patrol car.
The man who ran off was able to get back in the Subaru and the pair drove away.
Police spotted the Subaru several times as it travelled through the Ingle Farm area, but were unsuccessful in attempts to spike the vehicle's tyres.
A traffic patrol located the vehicle parked at a shopping centre at Walkley Heights just before 5pm. Again, the suspects tried to flee but were quickly arrested by police.
One police officer was punched in the face and suffered an injury to his hand during the arrest.
A 40-year-old Maitland man and a 42-year-old Northfield man were arrested and taken to the Lyell McEwen Hospital where they both required treatment for ingesting unknown substances. They have both been charged with a raft of offences including assaulting an emergency worker, endangering life, unlawfully on premises, driving disqualified and theft.
The men did not receive police bail and will appear in the Elizabeth Magistrates Court on Monday 6 July.
