Police are asking for the public's help finding a subway slasher.

They say he got into a fistfight with another man at the Nevins Street station in Downtown Brooklyn Tuesday afternoon.

He then pulled a knife and slashed the 27-year-old victim in the face.

That man was taken to the hospital, and is expected to be okay.
