The attack shut down roads and transit while police searched and secured the Côte-des-Neiges area.
MONTREAL, Quebec — A gunman killed a Montreal police officer and a civilian Monday before officers shot him dead during a confrontation at a Hilton hotel in the Côte-des-Neiges neighborhood, police said.
The attack triggered an emergency alert, temporary transit shutdowns and a broad police operation in a dense area of homes, businesses and major roads. Police Chief Fady Dagher said the slain officer was Constable Mohamed Lamine Benredouan, 34, and that another officer was seriously hurt but stable.
The call began around 11:35 a.m., when emergency dispatchers received a report that someone was sticking a gun out of a hotel window, Dagher said. Police went to the scene and came under fire. Officers returned fire and killed the suspect. Dagher said investigators had not confirmed the suspect’s motive. He also said officials did not yet know who fired the shot that killed the civilian.
Benredouan had been with Montreal police since 2021. Dagher said it was the first death of a Montreal officer in the line of duty in 24 years. “It’s a nightmare,” the chief said as he described the loss. Video posted online appeared to show a person wearing olive-colored clothing and carrying a long gun during the exchange, though officials continued to review footage and evidence.
Witness Jacob Coutu said he first heard four or five gunshots while working at a nearby construction site. Minutes later, he said, police arrived in large numbers and more shots followed. Coutu said he saw officers in a gunfight and estimated he heard 30 or 40 shots. Images from the area showed police vehicles, a helicopter overhead and people leaving nearby buildings.
The emergency alert told residents to stay indoors and avoid the area while officers searched for an armed and dangerous suspect. The warning led to temporary closures on the Décarie expressway and portions of two subway lines. Police later lifted the alert after saying the suspect had been neutralized and no second suspect was being sought.
Quebec Domestic Security Minister Ian Lafrenière said the case was turned over to an independent police watchdog, which investigates serious injuries and deaths involving police. He said the RCMP and other agencies were consulted before officials determined the shooting was not terrorism. Police forces in British Columbia were also warned about possible documentation calling for violence against police.
The investigation continued with questions still open about the civilian’s death, the suspect’s motive and the origin of any written material tied to the attack. Officials said the next steps include reviewing videos, collecting physical evidence and completing the watchdog inquiry into the police response.
