Woman sucker-punched in the head, robbed in NYC subway station: video

Disturbing new surveillance video released by the NYPD shows the moment a mugger sucker-punches a woman in an East Village subway station and rips off her backpack.

The 23-year-old victim was walking out of the 1 train station at 14th Street and First Avenue — looking down at her phone — a few minutes before 6 p.m. Sunday when the stranger ran up behind her and clobbered her in the side of the head, according to police and the video clip released early Tuesday. He then grabbed her bag, which contained a MacBook Air and debit and credit cards, and ran off, cops said.
