Police are looking for the man who slashed a 71-year-old woman on a 6 train in Manhattan.

Cops say it happened early Monday morning at the Bleecker Street Station in NoHo.

They say the alleged attacker slashed the woman with an unknown object before running off to get on a north-bound D train.

A man who works at a nearby store told us he wants to see more police at the station.
