A New York Police Department officer attacked a woman worker on a subway platform, then ran away grinning to himself, according to the New York Daily News.
An internal affairs investigation began on Thursday after the officer turned himself in. He was caught on camera leaving the scene of the attack, which took place around 2:30 a.m. on Dec. 23.
A 28-year-old female employee of the Metropolitan Transit Authority reported to police that she was attacked and slammed to the concrete on the southbound D train platform at the Tremont Avenue station. The man who attacked her wrapped his hands around her throat and choked her, she said. She was hospitalized for injuries to her neck and back.
Cameras in the station caught an image of the off-duty, out-of-uniform cop smirking to himself as he exited the turnstiles.
When police circulated the video, however, it became clear that the attacker was one of their own, a Harlem officer who the department declined to name.
Police sources say that the officer claims the MTA employee cursed at him and tried to steal his cell phone. No explanation was offered as to why he did not attempt to report the crime or remain at the scene.
