A 24-year-old woman was busted trying to light what appeared to be a Molotov cocktail in Times Square Friday night.

She tried to set fire to a rag stuffed into a liquid-filled glass bottle at around 10 p.m. Cops saw what she was doing and wrested the bottle from her, police said.

It was not clear whether the liquid in the bottle was explosive. The woman was undergoing a psychiatric evaluation at Mount Sinai West Hospital.
