Hundreds of New Yorkers were caught flaunting coronavirus social distancing restrictions in Brooklyn’s Domino Park on Sunday — and cops did little about it, according to witnesses.

The scene, captured on a video posted on Twitter, shows rows of people soaking in the sun at the riverfront park in Williamsburg despite City Hall’s professed crackdown on large gatherings — and Mayor Bill de Blasio’s initiative to have residents snitch when they see lockdown violations.

It’s an indication of how New York’s Finest continue to grapple with how aggressively to enforce the restrictions.

The video, shot from a moving car, shows clusters of people lounging in the park with the Williamsburg Bridge in the background, a number of them not wearing protective masks. The parkgoers, some alone, others in small groups — by all accounts a normal day in the park.

According to an eyewitness, the NYPD pulled up to the Brooklyn park and blared warnings about social distancing, an eyewitness told The Post.

The announcement was ignored, and when cops got out and walked into the park, they reluctantly told people to wear masks and left.

“The police showed up and told parkgoers to put on masks, but added that they wished they didn’t have to be there,” the witness said. “They said they were only telling people to cover their faces because the mayor has a hotline for people to snitch.”

The NYPD has been tasked with enforcing social distancing regulations, with violators facing summonses, fines up to $1,000 or even arrest.

The NYPD inspects nearly 14,000 public places, bars, restaurants, and supermarkets daily to ensure social distancing restrictions are being adhered to.

They’ve also moved in on rowdy crowds. On Saturday, dozens pf revelers were cited and two men were arrested at a raucous party at a Canarsie barbershop.

Three days earlier, three men were arrested at an unauthorized prayer gathering outside Chabad-Lubavitch world headquarters in Brooklyn.

But cops have often taken a kid-glove approach to enforcement. Since March 17, police have issued a total of 143 summonses and made 19 arrests tied to the coronavirus lockdown, NYPD stats show.

At an April 3 funeral in Queens, hundreds of mourners gathered on Atlantic Avenue, flaunting social distancing rules. At least eight police officers were at the scene and even directed traffic for the slew of bikers in attendance.

But no summonses were issued, police said.

The NYPD has also shown restraint responding to complaints of large crowds at Hasidic funerals in Brooklyn, blaring sirens instead of writing summonses.

However, the Domino Park Twitter video contrasts the hands-off approach cops took at the crowded park with the more intrusive response to crowds at Hasidic funerals.

The video shows the park revelers enjoying the sunshine unhampered, then turns to a large group of Hasidic Jews outside a funeral. Police are on the scene blaring their sirens.

Cops have recently moved in to break up groups of Hasidic Jews gathered at funerals of religious leaders, complaining that the crowds violated social distancing rules.

“This is shameful how the #Jewish people in #NYC are being outraged,” the post said. “Can we call this #Antisemitism? Or should we call it Jew Targeting? When will the Jewish people in #NewYork be able to live calmly?”

A spokesperson for Mayor Bill de Blasio said the video “does not portray the whole context” of the incident.

“Our officers were able to get all parkgoers wihtout face coverings to leave the park with no issue,” the rep, Olivia Lapeyrolerie, told The Post.

“We will continue to monitor this site closely to ensure New Yorkers are following social distancing rules.”
