This is the sickening moment a group of teenagers attack a Jewish man in the street, the 14th anti Semitic incident in New York in a month.
As the unidentified victim man walks past the gang on Christmas Eve in Brooklyn, a folding camping chair is thrown at his head.
He ignores it and walks on, but the group chases him down the street and the youths take turns to punch him.
A member of the group picks up the chair, runs up to the man and throws it at him again.
The group then flees the scene in the opposite direction.
The attack was the fourteenth documented incident of anti-Semitic violence in New York in the last four weeks.
It comes after Grafton Thomas, 37, was arrested after allegedly stabbing five people with a machete inside a rabbi's home last week.
Jewish Future Alliance founder Yaakov Behrman shared the street clip on to Twitter and wrote: "This incident demonstrates that there are many unreported incidents in New York.
"The attack occurred last Tuesday and was never reported to NYPD or media.
"I first learned of it Sunday evening and spoke to victim Monday and obtained footage."
The same group of teenagers were reportedly seen attacking a 56-year-old Jewish man on a nearby street shortly after.
The victim was punched in the back of the head then thrown to the ground.
A police report was filed but no arrests have been made. The case has been referred to the Hate Crimes Task Force.
New York Governor Andrew Cuomo spoke out on Sunday amid the rise in anti-Semitic violence in the city.
He said: "This is an intolerant time in this country.
"We see anger, we see hatred exploding. It is an American cancer that is spreading in the body politic."
New York Mayor Bill de Blasio called for an increase of police presence in the affected communities.
He wrote: "Anti-Semitism is an attack on the values of our city - and we will confront it head-on."
