Two people have been killed in Quebec City after a stabbing spree by a man dressed in medieval clothing and armed with a bladed weapon on Halloween.
Another five victims have been taken to hospital but there was no immediate word on their conditions, Canadian media reports.
Police have arrested a man on suspicion of carrying out the attacks in the historic Old Quebec neighbourhood, near Parliament Hill.
The first calls to police came in around 10.28pm, officers said.
The suspect was detained shortly before 1am near the city’s Old Port and police are asking those in the area to remain indoors. A possible motive for the attacks was not known.
Quebec City Police spokesperson Etienne Doyon told the Canadian Broadcasting Corporation that the suspect is a man in his mid-20s. Mr Doyon said the suspect has been taken to hospital for evaluation.
He added: “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.”
Officers earlier said they were looking for a man in medieval clothes who had left “multiple victims”, after being alerted to multiple attacks.
The investigation is ongoing.
