Police are hunting for party-goers that attended an out-of-control gathering on Saturday night.
Acting Insp. Chris Adams said police had launched Operation Esryn to target trouble-makers from the wild party.
Acting Police Commissioner Chris Dawson said it was one of the worst out-of-control parties the State had seen for several years.
“We will leave no stone unturned until we get to the bottom of those responsible for what happened on Saturday night,” Acting Insp. Adams said.
“We’ll be looking at those individuals in particular who threw rocks and glass at police officers and preferring charges accordingly.
“I give them this opportunity to hand themselves in to Cannington police station, or through their parents contact Crime Stoppers, because if they don’t hand themselves in, we will find them… and if the evidence exists we’ll put them before the courts.
“The behaviour is just disgraceful, to throw bricks and glass and signposts and debris at police officers, to damage community property, quite frankly is just unacceptable.”
Some of those who attended used Facebook to describe the violent event as one of the best parties "in a long, long time".
Several partygoers have posted on the Facebook pages of two teenage boys who organised the event expressing their thanks for hosting the gathering saying it was "mad" and suggesting the boys stage another party soon.
More than 70 police officers, including police dogs, horses and the airwing were called to quell about 500 people at a disused shed on Warton Road in Piara Waters in Perth’s southern suburbs about 9pm on Saturday.
Acting Insp. Adams said he had already viewed some of the footage and there were “quite a few people” who needed to be interviewed.
There were also rumours that several of the teenagers were planning another party and Acting Insp. Adams warned them against it.
“Any such party of this type of nature or unlawful gathering will be met equally by the WA Police and it won’t be tolerated, certainly the community doesn’t expect it to be tolerated,” he said.
A 15-year-old has been charged with criminal damage and assaulting a public officer after he allegedly smashed the window of an ambulance that was being driven through the crowd to get to the stabbing victim.Police have charged six others, including three juveniles, with unlawful assembly.
