NYC police have detained a man for a brutal attack on an elderly woman sitting on a subway train. Bystanders filmed the shocking assault, but did nothing to stop him.

The NYPD had sought the public’s help to identify the attacker, who repeatedly kicked a 78-year-old woman in the head while she sat on a northbound No. 2 train in the early hours of March 10.

The defenseless woman was sitting alone on the subway and attempted to block the attacker’s ruthless assault by shielding her face as he landed repeated blows to her head and body.

As shown in the footage, the attacker casually exits the carriage at the next station, apparently without any passengers attempting to stop him.

A bystander alerted an officer to the incident at that next stop, Wakefield Street Station, and the woman was treated by emergency medics for bleeding and swelling from cuts to her face, but refused any further treatment.

The horrifying footage sparked a social media campaign to identify the perpetrator.
