Toronto police say they have Tasered and arrested a man involved in suspicious activity outside the Canadian Security Intelligence Service office in downtown Toronto Tuesday.
The discovery of two black suitcases outside the CSIS office triggered the shutdown of Front Street West near the Metro Convention Centre about 8 a.m. this morning.

A robot and bomb disposal team checked the scene and re-opened the area around noon.

Police told CTV News they believe man who left the suitcases returned to the area shortly after 5 p.m. on Tuesday.

Police said he appeared agitated. To subdue him, police jolted him with a Taser. They took him into custody and then off to hospital for treatment and a mental health assessment.

The area around Front Street West from Simcoe Street to Blue Jays Way was closed for the police activity again during the evening rush hour.

John Street was closed as well, from Wellington Street West south to Front Street.

The drama began Tuesday morning, police were called in after a car and two black suitcases were left in front of 277 Front St. W.

Toronto's Emergency Task Force examined the suitcases and determined that they did not contain anything that could be considered a threat.

After investigation, they determined the suitcases contained clothing.

Police said at the time they were actively looking for the car's registered owner.
