A man has lost part of his ear after it was bitten off during a fist fight in Sydney’s inner west.

During the clash in Camperdown on Thursday, a 37-year-old man punched another man in the head repeatedly before biting off part of his right ear.

The man was arrested and charged with causing grievous bodily harm and refused bail to appear in Newtown Local Court on Friday.

The injured man was taken to hospital for treatment.
