Three men have been charged after allegedly throwing objects at police, in one instance injuring an officer who then needed hospital treatment, during an arrest at Windale in the early hours of Saturday morning.
Lake Macquarie police came knocking at about 12.40am at a property on Myall Street to inquire about unregistered motorbikes being ridden in the area.
When they arrived, police said in a statement, a 27-year-old man allegedly tried to flee but was arrested a short time later.
Police allege a 33-year-old then threw an object at a constable, causing a cut to his head that was later treated in hospital.
A 29-year-old is also alleged to have thrown an object at a senior constable as they made the arrest, but the officer was not injured.
Both men were arrested, and the trio taken to Belmont police station, where they were charged with a string of driving offences, possession of a prohibited drug, carrying a cutting weapon, and hindering police.
While the 27-year-old was refused bail by police, the older men were both granted strict conditional release to appear in Belmont Local Court on December 13.
