Montreal police are going door to door in the area and have set up a command post at de la Commune Street and Place Jacques-Cartier to get leads in connection with three incidents.

Project Trinité has led to 14 arrests and three arrest warrants in connection with a shooting in Côte-des-Neiges last October, say police.

With the cause of the fire unclear, the case file has been transferred to the SPVM's arson squad.

The apparent victims are not cooperating, according to police.

Montreal Mayor Valérie Plante said the city is increasing police patrols in key neighbourhoods following an uptick in violent crimes.

According to the victims, the suspect fled on foot before authorities arrived.

The 57-year-old was pronounced dead on the scene.

The incident took place on Des Récollets Avenue near Forest Street.

Police viewed video surveillance footage that showed a fight that broke out between several people right by the window that shattered.

Two 72-year-old men were taken to hospital following the incident.
