A man dressed in Medieval clothing attacked multiple victims with what police called a "bladed weapon" in Quebec on Saturday night local time, leaving at least two dead.

Police in the Canadian city reported the incident on Twitter shortly before midnight and urged residents to stay indoors while the suspect remains on the loose, the Canadian Broadcasting Corporation reported.

The incident took place near Parliament Hill close to the national assembly, police said.

According to Canada's CTV News, five victims were taken to a local hospital but there was no information on their conditions.

Authorities also did not immediately release details concerning the two people who were killed or say if there were additional victims.

"It remains to be determined, but these are serious attacks," police spokesperson Etienne Doyon told the station.

A man in his mid 20s was arrested shortly before 1am local time, officers said.

Reporters at the scene have tweeted photos of a police command post outside Quebec's Parliament Building.
