At least two people have been stabbed to death in the Canadian city of Quebec by a man armed with a sword and dressed in medieval clothing, police say.
Five others were wounded in the Halloween night attack. A man in his mid-20s was arrested shortly before 01:00 (06:00 GMT) on Sunday.
Police advised residents to stay inside with doors locked while an investigation was under way.
The attack took place in the historic Old Quebec neighbourhood.
Police tweeted that there was no immediate indication “that the suspect may have acted for motives other than personal ones”.
The suspect’s identity has not been made public.
First reports of the incident near the mostly French-speaking city’s Parliament Hill came through shortly before 22:30 local time on Saturday.
The suspect was arrested near the Espace 400e business park.
Quebec’s Le Soleil newspaper reported that he was lying on the ground, barefoot and hypothermic when he was arrested. He surrendered to police without any resistance, it said.
Following his arrest, the suspect was taken to hospital for “evaluation”.
The five wounded are also being treated in hospital, with varying levels of injury, according to police.
Police have not released details of the victims’ identities or ages.
Reporters at the scene have tweeted photos of a police command post outside Quebec’s Parliament Building.
At a news conference on Sunday, Quebec City police spokesman Étienne Doyon offered “sincerest condolences to the loved ones and families of the people who died”.
