Shortly after 9:15 a.m., members of the police tactical unit entered a building on St-Laurent Boulevard looking for the man who they believed had barricaded himself in a residence.
Police were first called to the building at around 11 p.m. Thursday night to settle a dispute between two individuals.
Police said threats were made during the argument and when officers attempted to arrest one of the individuals, they believed he took refuge inside a residence. For a time, officers were unable to contact him.
As police awaited a search warrant, they shut down sections of St-Laurent Boulevard and Pine Avenue to traffic.
Const. Yannick Ouimet said they had received tips that the man, who is in this thirties, might have been armed.
But when they entered the building and searched two apartments, police did not find the man, or any firearms, inside.
Const. Daniel Lacoursière said police are going to investigate further.
He said police are not sure if the man who was responsible for the threats is a resident of the building.
