Former Gov. David Paterson fought back against the miscreants who attacked him and his stepson on the Upper East Side on Friday night — with the ex-gov telling The Post that he slammed one of his assailants into a storefront window and punched him after the assault began.

“I threw him into the window of McDonald’s, I hit him again,” Paterson said Monday. “I put my hand on his face, and smashed him into the window. He fell to the ground.”

When a witness asked a stunned Paterson if his viciousness was necessary, the Democrat said, “Yes, they’re trying to hurt us!”

Four people have been arrested for the Upper East Side brawl, including Travor Nurse, a 40-year-old man accused of punching Paterson; a 34-year-old woman whose name has been withheld; and two boys, ages 12 and 13.

Paterson, who is blind in his left eye and partially blind in his right, said the two adults instigated the fight — including the assault on his 20-year-old step-son, Anthony.

“The adults can rot in hell as far as I’m concerned,” he said.
