Yesterday, the NYPD asked for the public's help in identifying the man who allegedly attacked an on-duty subway conductor at the East Tremont Avenue station in the Bronx. Now, WCBS 2 is reporting that a police officer recognized himself from the surveillance video and subsequently turned himself in.

According to to police, at 2:30 a.m. on December 23, a 28-year-old female MTA employee, who was on duty and in her full uniform, was "approached by a male on the southbound platform of the D Train at the East Tremont Train Station. The male grabbed the MTA employee in a bear hug from behind and pushed her to the platform floor, and then began to choke her."

The conductor had been on the platform to let passengers know about service changes. The Post's source said, "He was livid about the service and took it out on the conductor." The MTA workers' union, TWU Local 100, says that another conductor pulled the attacker off the victim. The injured conductor was treated for head, neck and back injuries at a hospital.

WCBS 2 reports, "The officer"—who was off-duty during the incident—"told investigators the woman cursed at him after he asked her a question, and grabbed his phone to prevent him from taking her picture, police alleged."

No one has been charged. Yet.
