Queanbeyan police were busy controlling parties at the weekend, which got out of hand thanks unexpected gate-crashers.
One party was broken up in Jerrabombera on Friday night, peaking at 200 guests, many uninvited. The party is believed to have been the work of a 16 year-old using Facebook to promote the bash.
Another party was broken up in Queanbeyan on Saturday night after a group of 40 partygoers, many uninvited, got out of control.
Both were broken up prior to midnight with a few arrests and minor property damage.
