A creepy commuter who enjoys gyrating against unsuspecting straphangers who were Harlem-bound ended up in handcuffs after his latest victim turned out to be a plainclothes cop, officials said Thursday.
Police arrested Osa Ayanru, 38, at the 59th St. station in Midtown after he zeroed in on NYPD Detective Jennifer Rosario at about 4:15 p.m. on Wednesday.
Rosario and her partner — who are assigned to the NYPD Transit Bureau’s Anti Crime squad — were on a Harlem-bound No. 6 train looking out for crimes on the rails when Ayanru approached and began rubbing his privates against her thigh as the train entered the 59th St. station, authorities said.
When the train stopped, Rosario whirled around and took Ayanru into custody, charging him with forcible touching and sexual abuse, officials said.
His arraignment was pending.
