Police say an overnight house party got so out of control Saturday night, 50 officers had to break it up.

On Saturday, the University of Waterloo and Wilfrid Laurier University held their annual homecoming weekend festivities.

“There was 700 people invited on Facebook,” said Amy Smith, a second year Laurier student.

Thousands celebrated during the day, and officers remarked on hopes for a calm, responsible weekend.

“We hope when somebody is thinking of doing something stupid, doing something unsafe, that they might turn around, see a police officer in the close vicinity and it might prevent them from doing that,” said Waterloo Regional Police officer, Ben Coles.

Police say they had a steady stream of tickets handed out for underage drinking and for having open liquor.
