A British Columbia hotel owner faces five charges of aggravated assault after a number of hotel employees were stabbed in a seemingly unprovoked attack over the weekend.

The stabbings took place at the Red Lion Inn and Suites in Saanich, B.C., on Saturday evening and sent five employees to hospital with stab wounds.

Police say all the victims have since been released from hospital.

Hotel guests were under lockdown for several hours as police scoured the hotel.

“No one was informing us about anything, we were just stuck in our room, not knowing what to do where to go,” Brittany Philbrook told CTV British Columbia.

Saanich Police Sgt. Chris Horsley said there didn’t seem to be any type of confrontation between the attacker and hotel employees before to the stabbings took place.

“No conversation or nothing prior to the assault,” he told reporters during a news conference Sunday. “They were simply doing their jobs at the Red Lion and they were stabbed.”

Horsley said the stabbings took place in the hotel restaurant before the attacker entered the hotel lobby and stabbed the front desk clerk.

Police have charged hotel co-owner Zhi Wei “Wally” Meng with five counts of aggravated assault.

Meng, 52, co-owns at least four hotels in the Victoria area. Police have asked for Meng to undergo a psychological review.

He is scheduled to appear in Victoria provincial court on Monday.

The Red Lion Inn and Suites has since re-opened.
