A man in his 20s is facing charges after causing a disturbance and producing a weapon inside the Winnipeg Police Service Headquarters.

Police allege that the man came into the front vestibule of the headquarters around 5:15 p.m. on Friday. The WPS says in a release that once the man was inside, he began to act erratically.

"The male’s behaviour escalated to punching and kicking at various doors and windows," police say. "He later pushed a panic button—causing an audible alarm to sound, at which time he aggressively brandished a knife while looking at police."

Police officers on duty in the building were able to safely take him into custody.

The WPS says that officers believe that methamphetamine use played a role in the incident.

A 27-year-old man from Winnipeg is facing charges of possession of a weapon.

He was released on an Appearance Notice as mandated by the Criminal Code.
