Longueuil police (SPAL) says a person who was exhibiting "threatening behaviour" Thursday morning has surrendered.

The incident happened on Saint-Charles Street near Roland-Therrien Boulevard in the Vieux-Longueuil sector.

Officers responded to the scene but said they had difficulty making contact with the individual, who was in a car.

The person surrendered after several hours of negotiations, and traffic was reopened to the public.
