New York Post:
Disturbing surveillance video shows a woman getting walloped without warning by a passerby in Brooklyn on Monday morning — the city’s latest case of unprovoked sidewalk violence.
The unsuspecting, 40-year-old victim was sitting on the stoop outside 418 Sterling St. in Crown Heights when a man she doesn’t know struck her on the left side of her face around 7:45 a.m., the NYPD said.
A video clip posted online shows the brute walking up and using his left hand to deliver the roundhouse blow.
The assailant — who was wearing baggy jeans and an oversize, white T-shirt — never broke his stride, but turned and looked over his shoulder as he continued along the block and out of camera range.
