A manhunt was underway Thursday in the eastern Canadian province of New Brunswick after a shooting rampage left three Royal Canadian Mounted Police officers dead and two others wounded.
Authorities were searching for the suspect, Justin Bourque, 24, who was wearing camouflage and carrying two rifles late Wednesday when witnesses say he began firing on officers in Moncton.
"Please continue to be vigilant.If you see anything call 911.Please do NOT post police movements on social networks." police said in a mid-morning tweet aimed at residents of Moncton, a city of almost 70,000 people less than 180 miles from the Maine border.
Earlier, New Brunswick police Commissioner Roger Brown tweeted: "It has been perhaps the darkest day in the history of the New Brunswick RCMP."
Mounted Police Constable Damien Theriault said Bourque is considered armed and dangerous. No motive for the shootings was released.
"I lost three friends," Theriault told Canada's CBC News. "And now we need to pull together and locate this individual as quickly as possible to ensure everyone's safety. "We are professionals and we have a job to do right now. We will have time to grieve after."
