suspected gunman who dressed as a policeman killed several people, including a police officer, in a 12-hour-rampage in Nova Scotia, Canadian media reports.
The attacker was captured by police on Sunday in the rural town of Portapique.
Residents had been advised to lock themselves indoors before the man was arrested following the attack.
Police said the suspect was driving what appeared to be a police car before changing to another vehicle.
Canadian Prime Minister Justin Trudeau described it as "a terrible situation" and Nova Scotia Premier Stephen McNeil told reporters "this is one of the most senseless acts of violence in our province's history."

Police say they were first alerted to an incident involving firearms late on Saturday.
Tweets by Nova Scotia police identified the alleged attacker as 51-year-old Gabriel Wortman.
He was not employed by the Royal Canadian Mounted Police but "may be wearing a RCMP uniform", they said.
