WATERLOO — Police had to summon every officer on duty early Sunday when confronted by a hostile crowd outside a Waterloo nightclub.

Eleven officers were eventually dispatched to the Brixton nightclub to arrest one suspect outside the bar at 140 University Ave.

The suspect is accused of pulling a knife outside the bar during a fight. He didn't use the knife and no one was injured. Police arrived after 2 a.m. as the suspect was about to drive away with two friends. He was arrested.

"A large group of patrons came from the bar and attempted to interfere, shouting, hurling insults at the officers, and filming the incident with cellphones within inches of the officers' faces," said Staff Sgt. Deborah McBride of Waterloo Regional Police.

Officers at the scene called for reinforcements. "When we have to bring in 11 officers to control a crowd, that's very concerning for us," McBride said. "That's all our units that we would have even had working … to deal with this because people were interfering with police.

"This was a very unusual reaction for us to be dealing with here in Waterloo, being surrounded like that at calls. I'm sure the officers were concerned for their safety."

The incident ended without further arrests. A Kitchener man, 19, is in custody awaiting a bail hearing, charged with possessing a dangerous weapon.
