Picture: Attila Szilvasi Source: The Sunday Telegraph POLICE have closed down the latest in a series of parties which have led to chaos and destruction in Sydney's northwest. The Hills police set up roadblocks to prevent revellers attending the so-called "bush doof" on a rural property on Glenhaven Rd, Kellyville. It was organised without the owner's consent, police said, and promoted on Facebook and other social media sites. It was to be "round seven" of a series which included last week's Constitution Hill party. Youths rampaged after police closed that party, damaging property and overturning cars. Three arrests were made. Last night police Inspector Helen Dean, at the scene, said on Facebook she was shocked that parents were dropping off children without knowing anything about the party. "When questioned these parents admitted they did not know the organisers or owner of the premises," she said. The owner of the premises was not aware of the party and does not know those who organised it. Police believe organisers of the Constitution Hill party were behind last night's failed festivities. "We nipped it in the bud tonight but if it had gone ahead and got out of control it probably would have tied up a lot more resources," Inspector Col Lott said. Two hours after the party was due to start The Sunday Telegraph spoke to several carloads of youths arriving every few minutes. The teenagers said they were simply "going for a drive" up the deserted, rural dead-end road. Insp Lott said parties advertised on social media often got out of control. Beaumont Hills teenager Brittany Rogers said she had heard about the party after "round six" last week through Facebook and friends. She said the previous parties had been wild but had been put on by different people. Police are now bracing for the "round eight" party.
