A joint LGBTQ and Black Lives Matter march in Manhattan on Sunday led to clashes with NYPD cops.

The crowd of hundreds — some of whom carried anti-police-brutality banners and waved rainbow flags — got into confrontations with officers after reaching Washington Square Park in the West Village from downtown Foley Square.

The tensions erupted after officers spotted 29-year-old Brooklyn resident Michael Dunn allegedly vandalizing a marked police car with black marker at about 4:30 p.m., law enforcement sources said.

Chanting “Hands up! Don’t shoot!,’’ the protesters clashed with the horde of cops,  screaming in their faces, video and photos show. Some of the marchers and cops were not wearing face masks.

At one point, a cop appeared to have been pepper-sprayed, and another fell off his motorcycle, as other officers pushed back the crowd, according to video.

Another officer was allegedly punched in the nose by Millen Dang, a 20-year-old from Brooklyn, who was later arrested, sources said.

At least one other protester, 25-year-old Jacob Kruger, of New Jersey, was arrested for allegedly assaulting a police officer outside the park.

The march was organized by the Reclaim Pride Coalition and called the Queer Liberation March.

It was held the same day the city livestreamed a virtual Pride celebration, to replace its famous annual parade, because of the coronavirus.
