Toronto police say they've identified a woman who allegedly threw a chair from the balcony of a downtown highrise.

Const. David Hopkinson says they've been in touch with the woman and are arranging for her to turn herself in.

A video circulating online Monday showed a blond woman tossing a chair and other unspecified items from the balcony toward a nearby highway.

Police say they believe the incident occurred on Saturday, with the chair landing in front of a building entrance and no reports of injuries.

They are investigating the incident as a case of mischief endangering life.

Hopkinson says investigators want to hear the woman's side of the story before laying charges.
