A screenshot of video of the attack
"The attack occurred at 7:40 p.m., on the corner of Marcy Avenue and Rodney Street. Surveillance video shows a 39-year-old Hasidic man walking down the street when a dark-skinned teen comes up behind him and wordlessly slaps him on the side of his face, before fleeing. The man stumbled and fell against the wall of a building, and his hat and yarmulke were knocked off and before he could turn around, the attacker fled. There were no words exchanged. The NYPD's Hate Crime Task Force is investigating this as a possible bias incident..."
