NEW YORK — NYPD Commissioner Jessica Tisch has launched an investigation into a caught-on-camera clash where a rowdy crowd pelted a group of uniformed cops with snowballs in Manhattan’s Washington Square Park.

“The NYPD is aware of certain videos taken earlier today in Washington Square Park showing individuals attacking cops,” Tisch wrote on X late Monday. “I want to be very clear: The behavior depicted is disgraceful, and it is criminal.”

“Our detectives are investigating this matter,” she added.

Mayor Zohran Mamdani last month told school children they could throw snowballs at him for enacting mandatory remote learning on a snow day.

He took a lighter tone that Tisch when talking about the Washington Square Park incident.

“I’ve seen the videos of kids throwing snowballs at NYPD officers,” Mamdani posted on social media. “Officers, like all city workers, have been out in a historic blizzard, keeping New Yorkers safe and cars moving.”

“Treat them with respect,” he added. “If anyone’s catching a snowball, it’s me.”

Cops were responding to 911 calls of a large disorderly crowd throwing snowballs from the top of the park’s bathroom and jumping off the roof about 4:15 p.m. Monday, a police spokesman said.

When cops arrived at the scene, they saw 50 people, mostly teenagers and college-age men, engaged in the heated snowball fight and called for backup.

That’s when “multiple uniformed officers were struck in the head at close range with snowballs, causing injuries to the head, face, and neck area,” an NYPD spokesman said.

A pre-planned snowball fight was taking place in the park as cops arrived.

Video uploaded to social media show the officers being battered by snowballs outside park restrooms as dozens of parkgoers crowd around filming and jeering at the cops.

“F–king bitch,” one man can be heard screaming at the cops, while another yelled: “Get em out of here.”

One cop was repeatedly hit by snowballs, the video shows. At one point, someone runs up behind the officer and smashes a snowball into the back of the cop’s head.

Cops were recorded shoving two people out of the way as they walked through the gauntlet of snow hurlers.

The NYPD said that “multiple uniformed officers” were taken to Northwell Greenwich Village Hospital, where they were treated for facial injuries.

“Our police officers are being treated for their injuries, but the case CANNOT end there,” the Police Benevolent Association, the NYPD’s largest union, posted on social media. “The individuals involved must be identified, arrested and charged with assault on a police officer.”

The union called the incident “unacceptable and outrageous,” adding, “This is the environment that NYC police officers are up against.”

The pelting occurred amid a pre-planned snowball fight inside the West Village park following a blizzard that dumped nearly 20″ of snow on the city.

Many of the people throwing snowballs came from NYU, police believe.

“While some people may attempt to dismiss this incident as college hijinks or harmless kids throwing snowballs, the deliberate targeting of uniformed police officers by hurling objects at them while they perform their lawful duties constitutes an assault,” NYPD Sergeants Benevolent Association President Vincent Vallelong said in a statement to his members.

He added that the snowball hurlers crossed “a clear line.”

“The behavior of the people throwing the snowballs, many of whom are believed to be NYU students, was reckless and unlawful, and put the lives and safety of others at risk,” he said. “Today it is snowballs. Tomorrow it could be rocks, bottles, or worse.”

The snowball fight began at 3 p.m. and was organized by Side Talk, an online video series.

An email to organizers was not returned.

Other videos show cops being followed out of the park to a marked NYPD van as gigantic snowballs rain down upon them.

“The Detectives’ Endowment Association is calling on Mayor Mamdani and District Attorney (Alvin) Bragg to ensure every individual responsible for this illegal behavior is prosecuted,” that union’s president, Scott Munro, said in a statement. “No free pass. No get out of jail free card.”

As of Tuesday, no arrests have been made, an NYPD spokesman said.

City Council Speaker Julie Menin, D-Manhattan, blasted the snowball hurlers on X.

“These are public servants who are out in the cold, in all kinds of conditions, to keep New Yorkers safe,” she wrote. “Causing injuries to officers is not a game. We cannot normalize this kind of behavior in our city.”

The union demands were ridiculed on social media, with some calling the pelted officers “snowflakes” and encouraging the cops to “play along next time.”

“No one wants to fund thousands in investigations over two guys trying to break up a snowball fight,” one X user, who goes by the handle “Ghost Money” wrote. “You guys have the worst PR.”

“Even my dad, who spent 33 years as a police officer here in Ohio before retiring, said these officers brought this on themselves,” user @armystig wrote. “The kids were outside and having fun in the park on a snow day. There was no need for them to stick their noses into this. Let the kids have their fun.”

“There’s a beautiful metaphor here,” added Todd Bonzalez. “When a bunch of snowflakes (you all) stick together, you form a snowball.”
