A school formal after-party has descended into chaos after gatecrashers stormed the party armed with machetes in Adelaide’s northeast, causing thousands of dollars in damage.

Shocking CCTV footage showed the intruders storming the formal after-party about 10pm on Friday in Hillcrest.

Party host Jaycon Coller said two cars pulled up outside the property, with several people piling out and demanding to come inside.

The intruders then kicked the door in and began searching for someone at the home, leaving chaos and destruction in their wake.

Footage showed one of the intruders carrying a baseball bat as he entered the property, with another uninvited person carrying a machete.

Mr Coller told 9News that he stipulated there would be “no fighting” when organising the party, but the message went unheard.

“They’ve forced their way in by kicking the front door open … coming in with baseball bats and machetes, swinging it at everyone and yelling out a particular name,” he said, adding the intruders caused thousands of dollars in damage.

CCTV footage showed a sea of youths rushing out of the property a short time later, and while people a white car tried to flee, a person smashed the car window with a baseball bat.

A fight later broke out on the streets, with footage of a girl being dragged by her hair and “slammed to the floor” uploaded onto social media.

Neighbour Janine Donato described the disturbance as “crazy” and a “racket”, with a wave of high school students fleeing the house.

“This is normally a quiet area,” she said.
