A suspected gunman believed to be dressed as a police officer has been captured after several people were shot in Nova Scotia, Canadian police say.
Police have not confirmed the number of injuries or whether anyone has died.
Residents in the rural town of Portapique had been advised to lock themselves indoors or shelter in basements while the man was at large.
Police said the suspect had been driving what appeared to be a police car before changing to another vehicle.
They 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.
"There's one difference between his car and our Royal Canadian Mounted Police vehicles: the car # [registration plate]. The suspect's car is 28B11, behind rear passenger window. If you see 28B11 call 911 immediately," they tweeted on Sunday.
The gunman later changed cars to drive a "small silver Chevrolet SUV", police added.
