In the past three weeks, around the Jewish celebrations of Hanukkah, at least 14 disturbing anti-Semitic attacks have been reported in New York, according to the Washington Examiner.

The latest known was one that occurred Dec. 24, although it was not until Monday—after the release of the surveillance video—that the episode became known.

The security footage shows seven teenagers walking down a street when they encountered an Orthodox Jew who crossed them in the opposite direction. As he was walking, one of the group members threw a chair at him.

Several of the teenagers tried to jump the man from behind as he continued to walk. When he turned to face them, one of the teens threw a punch at him while another hit him with the chair again.

The video was posted on Twitter Monday by Yaakov Berhrman, who founded the Jewish Alliance of the Future. ” I found disturbing footage of chair throwing & assault on Chassidic Jew Tue on Albany & Lincoln. Victim is uncomfortable reporting due to the discovery reform (attacker may know his identity). Same group assaulted someone later that night on Union Kingston.”
