The Halifax Regional Police forensic identification unit and the medical examiner are on the scene of a suspicious death on Cook Avenue in Halifax.

Officers were called to a home in the 6900 block around 8:00 p.m. on Sunday, where they found the body of a man, who they believe to be in his late 20s.

At least six police vehicles were still on the scene around 9:30 p.m. The K-9 unit was also called.

Monday morning investigators were taking pictures and appear to be looking for fingerprints on the front door of the home, officers are also examining a vehicle parked in the driveway.

Police have closed a section of Cook Avenue where it meets Romans Avenue.

Residents who live in the neighbourhood said police with guns drawn came to their doors to tell them to stay inside.

"I went over shopping and I came over to Romans Avenue, and there was a cop right at the end there with the lights flashing," said Shirley McDougall.

"I'm kind of worried now, because I know a lot of people on this street."

Colleen Murphy Jones said police told her that she was safe but the investigation would take some time.

"The policeman came to the door and asked if I'd heard anything, and I said no, I hadn't heard anything at all. But I think there must have been a gunshot, because he said, did I hear a 'pop, pop.' I had not heard that."
