MONCTON, N.B. -- The RCMP is investigating the suspicious death of a man in Moncton.

Police responded to a 911 call at an apartment building on Essex Street around 3 p.m. Thursday.

When officers arrived, they found the body of a man outside the building, near the entrances to two units.

Jamal Hebert and his brother watched the heavy police presence from their home across the street last night.

"A bunch of cops, and I was like 'oh my god what's going on?'" Hebert said.

The 42-year-old man has not been identified, but investigators say he was from Ontario.

There has been a heavy police presence at the apartment building since Thursday afternoon, with crime scene tape surrounding the scene.

Some people who live in this area say it's usually a quiet neighbourhood and this type of activity comes as quite a shock.

A cause has not been released, but police say they are treating the man’s death as suspicious.

Some say not having the answers this close to home has put them on edge.

"Anything could happen really," said Bradley Hebert, who lives nearby. "It's really close. The people that did it could still be around."

Police have not said whether they are searching for a suspect, or suspects, in connection with the incident.

RCMP are appealing to anyone who has information or who saw anything on Essex Street around 3 p.m. Thursday and encouraging them to contact the RCMP or Crimestoppers.
