ALBANY — Windows were broken, walls were spray-painted and a door was defaced at a historic Republican club in Manhattan Thursday, and Republicans claim it was done by radical leftists.

Police on Friday confirmed there was an incident but didn't speculate regarding a motive and didn't comment further. There were no arrests.

State Republican chairman Ed Cox, at the East 83rd Street building on Friday, said, “In the middle of the night, the New York Republican New York City headquarters at the Metropolitan Republican Club was physically vandalized by anti-Republican forces.”

Cox said the spray-painted damage included symbols used by the antifa, a term for left-wing, anti-fascist groups. Cox also said the damage included anarchist symbols and a note that warned the “attack is merely the beginning.”

"Governor Cuomo has said conservatives have no place in New York and the inciteful rhetoric ... is dangerous and must be stopped before someone gets hurt," Cox said.

Republican candidate for governor Marc Molinaro called the violence unacceptable and called on his opponent, Democratic Gov. Andrew M. Cuomo, to “call for calm on the political left.”

Democrats issued a measured statement.

“New York Democrats have zero tolerance for violence in our political system and condemn this latest act of vandalism,” said Geoff Berman, executive director of the state Democratic Committee, headed by Cuomo. “This type of divisiveness is repugnant to everything we believe as New Yorkers. That being said, Ed Cox and Marc Molinaro's rhetoric on this is wildly inappropriate. We need less hate and division — not more.”
