It got a little nerve-wracking for some Aberdeen neighbours Saturday night who believed the police couldn't come quickly enough when 200 youths converged on their street.
"There were beer bottles, they were young and a lot of people," said Mary-Lou Ryant.
But in the end, the 2000 block of Westerdale Court returned to relative calm with little fuss.
"I was really grateful when the police came," said Ryant. "I didn't want to call the police myself, but the police came and cleared everybody out so I think it could've been way worse."
The horde had gathered after a Facebook page was created announcing the party. The owner of the party's location told police the plan was for 20 guests.
Police had advance warning of the event when a complaint was called in to the Kamloops RCMP detachment just after 9 p.m., according to Staff Sgt. Lane Jumaga.
Neighbours noticed the crowd starting to gather at around 8 p.m. and by 9:30 p.m., police were able to quietly and calmly drive off the 200 youths.
The street's residents hadn't seen a gathering of that scale in recent memory, according to Ryant.
And the homeowner reportedly got an earful for it.
"Some residents in the area had already expressed that they were upset (when the police arrived)," said Jumaga.
