Police are searching for a man who groped a 38-year-old woman on an E train in Long Island City.

The man, described as in his 50s with glasses, approached her on the eastbound train as it pulled into the Queens Plaza station at about 4:40 p.m. on March 22.

He then put his hand on her groin, police said, and got off the train at that station.

There were no arrests as of Tuesday.
