Video clips obtained by The Post and posted online show a heavy police presence amid a chaotic scene in a Hasidic Jewish neighborhood in Brooklyn on Thursday afternoon — two days after a massive funeral there that drew big crowds despite coronavirus restrictions.

In one clip, horns honk, people shout and sirens wail as a cop orders bystanders, “Back up! Back up!” in front of the Judaica Corner store in Borough Park.

“This is getting violent over here. They just arrested somebody,” a narrator says.

Another clip, recorded from inside a vehicle and posted on Twitter, shows police tape stretched across a street and a cop ordering the driver, “Keep going straight! Keep going straight!”

A source said the incident involved a funeral procession.

The chaos unfolded in the wake of a “zero tolerance” warning from Mayor Bill de Blasio to New York’s “Jewish community, and all communities” regarding violations of social distance rules.

The controversial threat followed a mass gathering Tuesday of thousands of mourners outside the Williamsburg funeral service for a prominent rabbi, Chaim Mertz, who died of the coronavirus.

A spokesperson for the NYPD said cops responded Thursday to a synagogue on Kent Avenue in Brooklyn, where they issued two summonses over doors being chained from the inside. Another summons was issued for social distancing.
