A Crown prosecutor says a young woman who threw a chair off a downtown Toronto high-rise balcony is "lucky she didn't kill someone."

A sentencing hearing for a woman, known as “Chair Girl,” who pleaded guilty to a mischief charge for tossing a patio chair off a downtown Toronto highrise balcony has been delayed until Feb. 7.

Investigators said the accused is facing three charges including mischief endanger life, mischief damage property under $5,000 and common nuisance.
