A two-hour standoff between police and a man armed with a knife in a parked car in Old Montreal ended Friday evening when he was subdued by officers armed with stun guns.

The man had threatened officers who approached him, Montreal police said, sparking a police response that involved calling in the SPVM's tactical unit and an armoured vehicle.

Montreal police spokesperson Const. Benoit Boisselle said the suspect was uninjured and was taken to hospital for a psychiatric evaluation.

Police cordoned off the area surrounding the man's vehicle, which was parked in a lot at the corner of St-Jacques and Gauvin streets.

A number of streets were closed in the vicinity of the parking lot, but they are all now open to traffic.

Police had to escort workers leaving their nearby offices at the end of the work week, to ensure their safety.
