Sicko on the 7 train

COPS ARE searching for a sicko straphanger caught pleasuring himself on a Flushing-bound No. 7 train in Queens, police said Wednesday.

Police released photos and a short video of the creep (inset) — filmed by a stunned commuter — in the hopes that someone recognizes him.

The man was seen touching his genitals over his clothes as he leered at a 29-year-old woman and other women passengers as the train moved between Queensboro Plaza stop and the 33rd St./Queens Blvd. station about 2:10 p.m. on Aug. 31.

He ultimately exited the train at 52nd St./ Roosevelt Ave. stop. Cops described him as a white man, about 35 to 40, between 5-foot-9 and 6-foot-1 and about 190 pounds.
