Police are looking for a man who groped a woman in the subway last month.

The suspect accosted a 47-year-old woman on the stairs of the 21st Street–Queensbridge F train station in Long Island City during the morning rush on July 30, police said.

He then grabbed the woman’s rear end and fled on foot, according to the NYPD.

A security camera image of the maskless suspect was released by police Thursday.
