A man has been charged with mischief in relation to the discovery of a package on the steps of Toronto police headquarters on Thursday afternoon, prompting the bomb squad to destroy the item.

The suspect was taken into custody at about 4 p.m.

College Street reopened to all traffic at about 4:15 p.m.

The man faces one count of mischief interfere with property. He has been identified as James Rockwood, 50.

He appeared in court at Old City Hall on Friday morning.
