NYPD Detective Jennifer Rosario was on the job, keeping an eye out for crime while riding a Harlem-bound subway in Manhattan on Wednesday, reports the New York Daily News. She just probably didn't imagine she'd be the victim. Police say the plainclothes officer felt something repeatedly touch her thigh while riding the Lexington Avenue line around 4:15pm and looked down to see a man's exposed penis, reports the New York Post. Osa Ayanru, 38, who police say was carrying a stun gun, was swiftly arrested and charged with forcible touching, sexual abuse, and possession of a weapon. (More New York City stories.)
