LONDON, Ont. — A 71-year-old woman is accused of tossing a Molotov cocktail at an upscale house that has been the target of arson as many as six times over the past two years, police say.

Firefighters and police responded early Sunday and stopped the flames from spreading from the garage to the house.

Sandra Park is charged with arson endangering life.

Police said it wasn't a random attack and that Park doesn't live at the address.

The fire was at least the third suspicious blaze on that street— and the second at that specific residence — over the past few months.

Police haven't said whether Park is being investigated for the other fires.
