Gatecrashers found out about the partyTwo people have been charged after a teenager’s party got out of control in Medina last night.
Specialist officers from the regional operations group and the dog squad were sent to the Peake Way property after reports of more than 100 teenagers fighting at the party about 9.30pm.
The party, hosted by a 15-year-old girl, had been posted on Facebook but as a private event for about 50 of her friends.
The girl told thewest.com.au she did not know how gatecrashers found out about the party which was meant to bring together her friends during the school holidays.
Partygoers clashed with police, allegedly throwing bottles at officers and vehicles.
Broken glass and smashed up cans were scattered along the road this morning.
Gatecrashers also set fire to a discarded sofa which had been put out onto a nearby verge for collection.
Firefighters were forced to wait until police made the area safe to extinguish the blaze.
