Toronto police say they have identified the woman who was filmed in a now-viral video throwing a chair from a balcony onto the Gardiner Expressway over the weekend.

Police have not publicly named the woman, who allegedly threw several items including two chairs from around the 45th floor of a high-rise on Bremner Boulevard.

A source tells CityNews the woman has a criminal history and police have been in touch with her. Officers are giving her about 24 hours to turn herself in.

The video, believed to be posted on Snapchat, shows a blonde woman standing on the balcony of a condo building holding a patio chair before launching it over the edge of the railing.

No injuries were reported in the incident which is believed to have happened at 10 a.m. on Saturday, with the chair landing next to a bike rack at the front entrance of the condo building.

Police say the woman is wanted for mischief – endanger life. They are also looking for the person recording the video.
