A perverted creep held his cellphone under a woman’s dress aboard a No. 7 train in Queens and recorded illicit video, police said Monday.

The suspect approached the 30-year-old woman on June 30 at about 10 p.m. on the northbound train near the 45th Road-Court House Square stop and recorded underneath her dress, cops said.

She got off the train at her stop and reported the incident to the MTA online, police said.

Police are looking for the suspect, who was last seen on the train, authorities said.

He was last seen wearing a gray T-shirt, green hat and green trousers, police said.
