The deranged woman who allegedly threw bleach on a woman in an unprovoked attack in a Manhattan subway station this week was arrested Friday, the NYPD said.

Lakeesha Tyler, 46, was hit with an assault charge for the attack, police said.

Tyler is accused of randomly throwing bleach in the 37-year-old woman’s face while she was standing on the northbound No. 1 train platform at the 14th Street and 7th Avenue subway station Thursday, cops said.

The victim was brought to Lenonx Healthplex with burns to her face.

Tyler was awaiting arraignment Friday night.
