Bengaluru: In a shocking incident being reported from the province of Nova Scotia, Canada, a gunman who disguised himself as a policeman shot down 16 people, including a policewoman in a 12-hour rampage. 

The incident took place on April 19. 

Nova Scotia RCMP chief superintendent Chris Leather confirmed there were at least 13 people killed in several locations across the province, including an RCMP officer, a popular website added.

Leather said that there may be more victims who have not been discovered yet and their investigation is continuing.

The gunman was identified as Gabriel Wortman, 51. His shooting rampage began late Saturday night in Portapique, about 130 km north of Halifax, the capital city of Nova Scotia, the website noted. 

Police first responded to a firearms complaint at a residence after receiving several 911 calls. They rushed to the residence, finding "several casualties" inside and outside of the home.

The policemen chased the gunman while exchange of fire took place. Finally, he was killed near a gas station about 35 km north of Halifax. 

"The fact that this individual had a uniform and a police car at his disposal certainly speaks to it not being a random act," Leather said.

In a statement, Canadian Prime Minister Justin Trudeau offered his condolences. "My heart goes out to everyone affected in what is a terrible situation. I want to thank the police for their hard work and people for cooperating with authorities."

Brian Sauve, president of Canadian National Police Federation union, in a statement, said, "Our hearts are heavy with grief and sadness today as we have lost one of our own. Our thoughts go out to our member's family and friends.”
