Dozens of revelers were hit with summonses and two were arrested on firearms charges after cops broke up a raucous party at a Brooklyn barbershop during the coronavirus lockdown.

The defiant partiers began filing in the eNVee Barbershop in Canarsie around 6 p.m. Saturday for a rap music video shoot that quickly turned into a party, as music blasted from the single-story shop on Avenue L, residents told The Post.

The NYPD issued 68 summonses and arrested two of the attendees for gun possession, police from the NYPD’s 69th Precinct wrote on Twitter above a photograph of the alleged weapon.

Under the coronavirus lockdown, residents must remain six feet apart while in public and gatherings of any size have been banned outright. Offenders face fines up to $1,000.

In response to the illicit shindig, Mayor de Blasio said Sunday cops would keep breaking them up.

“I’m going to keep breaking those things up,” de Blasio said at a news conference.

“If people need summonses to get the message, we’ll do it,” he said. “And remember also, in terms of the guns that they picked up, policing goes on. The fight always to protect public safety goes on.”

Reports of speakeasy restaurants and underground carousing have circulated as government officials try to keep people separated to quell the spread of the deadly virus.
