“Mayhem”

POLICE have been pelted with bottles and fireworks during a riot after a massive Facebook-organised party called “mayhem” in an unoccupied Melbourne home.

Up to 400 teenagers clashed with police after partygoers set off fireworks and gatecrashers showed up at the Glen Waverley house.

About 700 people had been invited to the party, mostly through Facebook, according to a group of youths who returned to the house on Saturday.

“They called it mayhem,” one teenager said of the Facebook invite.

“It’s also written inside on the walls.”

The youths, who didn’t provide their full names, say there may be “mayhem round two”.

Neighbours said the event had been advertised on Facebook as an end of year 12 and Halloween party.

People were lining up to get into Friday’s party and were being charged for entry, before gatecrashers turned up about 11pm, the youths said.
