Elderly Man And Teen Attacked In Out-Of-Control Melbourne Party

An elderly man and teenage girl have been assaulted at an out-of-control house party in east Melbourne.

A man has been assaulted on a Melbourne street during an out-of-control house party at a rental property.

The Hawthorn East rental was badly damaged by the time partygoers cleared out by 6am on Sunday following several noise complaints, police said.

A man aged in his 70s, believed to be a neighbour, was hospitalised with head injuries after being assaulted while a 16-year-old girl was also attacked.

A group of females is believed to have been behind the assaults but nobody has been arrested yet, police said.

In a statement, Victoria Police said they were "not aware of any criminal activity taking place", but the property had been left badly damaged.
