2000 FACEBOOK PARTY ANIMALS; CHAOS AS DRUNKEN REVELLERS PELT COPS.
POLICE were pelted with bricks and bottles as they cleared more than 2000 drunken revellers from an abandoned building.
The crowd, in their teens and 20s, gathered for the bash after it was organised via social networking website Facebook.
But firefighters, ambulance crews and police were called to the four-storey building in Mayfair, central London, amid safety fears as people began gathering on the roof.
At first, police were unable to get in because of the barrage.
Some revellers were even seen taunting them by mooning at them from the roof and balconies.
Eventually, officers used loudhailers to order everybody out. The area was cleared by around 1am yesterday.
A force spokesman said that nobody had been arrested, though they were trying to trace the party organisers.
A spokesman added: "The overriding concern was to ensure the safety of people inside the premises, as the roof was thought to be unsafe."
Terrified local residents said it was as if the partygoers had "materialised out of thin air" at around 11pm on Thursday.
Cabbie John Morris, 67, said he saw up to six youths jumping on the roof and the bonnet of his car after noise from the party woke him up in his flat.
He said: "They were so drunk they didn't know what they were doing."
Another neighbour said: "I went out at about midnight to have a look and there must have been as many people outside as there were in the party.
"They were all off their faces. They were running away from police, throwing things at them and urinating on the pavement.
"Some boys even mooned the riot cops.
"The organisers were charging pounds 3entryandtheyhadprofessional cameras to record the carnage."
