A crazed woman threw bleach at a stranger in an unprovoked attack in a Manhattan subway station on Thursday, police said.

The 37-year-old woman was leaving the 1/2/3 station at 14th Street and Seventh Avenue at around 12:40 p.m. when the unidentified attacker hurled bleach at her face before running away, cops said.

The victim suffered burn injuries to the face and was taken to Lenox Health Center to be treated.

Police are investigating.
