FIVE people were arrested and teenage girl fined $1000 after Police broke up a Halloween party attended by more than 100 people in Lake Macquarie on Friday night.
Officers from Lake Macquarie Police District were called to a home on Lake Road in Glendale about 6.45pm following reports of a backyard party.
More than 100 people were in the backyard of the property, Police said.
Some partygoers knocked down a fence and ran into adjacent streets and a nearby shopping centre, where multiple fights allegedly broke out.
Police intervened and broke up the altercations, arresting four teenagers and a 20-year-old man.
The man was taken to Belmont Police Station where he was issued with two Criminal Infringement Notices (CINs) for offensive language and offensive behaviour.
During the arrests, three police officers sustained minor injuries, with one requiring medical treatment.
