A Castle Hill man will appear in court after Saturday’s out-of-control party in Berowra where the NSW riot squad was called.
The 19-year-old Castle Hill man was celebrating his birthday with friends at the Berowra Community Hall when the party and became disruptive.
Police said the party was gate crashed by a number of people and when they arrived there was a total of 200 people outside and inside the venue.
Police arrested a 17-year-old Hornsby man and issued him with a criminal infringement notice after he allegedly made threats towards police and ran away before being caught.
Hornsby Council said the party was meant to be a pre-paid event but got out of control following a social media invite.
Hornsby mayor Nick Berman said he was angry and disappointed that the party organiser failed to abide by the terms and conditions of hire.
“The council has these rules and regulations for a reason,’’ councillor Berman said.
Prior to the party, the council agreed to lease the venue to the organiser, on the condition that paid security staff be on the premises and that no advertising take place on social media.
A council spokesman said police were aware of the booking and conducted background checks last week but found no reason why the party should be prevented.
The community centre sustained extensive damage from the event and police are continuing their investigations.
