Possible suspicious package in Plateau disrupts traffic

Montreal police are investigating after a suitcase was left on the sidewalk in front of an armoury in Montreal's Plateau neighbourhood. 

A large perimeter has been set up on de Bullion Street near the corner of Saint-Joseph Boulevard, disrupting traffic.

The tactical unit is on the scene. 

It is not clear if the package is dangerous, if it's a prank, or if it was left there accidentally.
