A man dressed in medieval clothing killed two people and injured several others in a stabbing rampage near the provincial legislature in Quebec City on Halloween night.

Police arrested a suspect in his mid-20s but told residents in the mostly French-speaking Canadian city to remain inside with the doors locked because an investigation was underway.

Five victims were taken to a local hospital, but their immediate condition was not known, police spokesperson Etienne Doyon told CBC News.

“On behalf of the Quebec City police, I want to offer my sincerest condolences to the loved ones and families of the people who died today,” he said.

The victims were not identified.

There were no details on a possible motive for the stabbings and it remains unclear if the attacks were random.
