A police officer was badly cut in the head by a bottle thrown from a Pt England party that turned violent after a man and a woman began arguing outside.
The gathering, in Taurima Ave on Saturday night, was a farewell for Alom Williams, 23, who is leaving for North Queensland. But it erupted into violence about 5am yesterday.
Mr Williams said a male relative and his partner were arguing outside and the man was attacked by several people.
A brawl started, and at least one person was stabbed with a broken beer bottle.
"We heard this girl screaming. These two girls were punching this dude [his relative] and he was standing back with his hands up. Then these other guys, brothers of one of the girls, jumped in and it went from there."
