A 28-year-old man is dead after police responded to a call regarding a domestic dispute in Ile-Bizard.

At 2:00 a.m., police received a call regarding a conflict between the man and his parents in a home on Place Monk. When they arrived, they found the man aggressive and under the influence of alcohol and drugs.

Ile-Bizard Mayor Normand Marinacci was among the neighbours who heard police arrive on the scene.

"We were woken up by sirens and police officers with the red lights on," he said. "It was not one or two, maybe seven. I said to myself 'Maybe the police are after someone, trying to track him or something.'"

When police officers attempted to restrain the man, he went into cardiac arrest. He could not be revived in the ambulance and was pronounced dead in hospital.

Marinacci described the family as "good people."

"My first thought went to the family," he said. "Losing a child like this at 28 years old in those circumstances is very sad."

Police say the two officers who tried to subdue the man are in shock.

The case has been transferred to the Bureau of Independent Investigators, which has set up a command post near the home.

Eight investigators from the bureau will look into the case to see if police intervened correctly. An autopsy will be performed on the man to determine if there was an underlying medical issue or if the death could have been prevented.
