The "well-dressed groper" responsible for attacks in the Upper East Side in February has turned into a serial sexual predator, according to the NYPD.

Most recently, CBS reports, a 22-year-old woman was touched between her legs while inside the Chambers and Center Street subway station near city hall.

The first incident occurred Feb. 25 at East 62nd and Park in the Upper East Side when a 33-year-old woman was approached from behind by a man and grabbed on the inner-thigh. The man then ran off.

A few days later, a 19-year-old was grabbed by the buttocks near East 67th Street and Second Avenue.

The suspect-- wanted in connection with four separate groping incidents-- is described white, clean shaven and well-dressed, with brown hair, 5 feet 11 inches tall, and 180 pounds. Cops have released surveillance footage of the man (see above).

Last summer, a "pint-sized pervert" went on a groping spree in the Upper East Side, claiming at least 10 victims. And in Brooklyn, another groper (not this guy) was suspected of 20 attacks in and around Park Slope.

Anyone with any information regarding the well-dressed groper should call 1-800-CRIMESTOPPERS.
