An antisemitic maniac wearing a shirt with the flag of Iran on it assaulted three Jewish men in Brooklyn on Friday while screaming hateful words at the victims, according to police and sources.

The brute, Andrzej Wnuk, 41, allegedly pummeled three men – a 48-year-old, 38-year-old, and 21-year-old – in the vicinity of Throop Avenue and Gerry Street in Williamsburg around 6:45 p.m. on Friday, cops said.

All three victims of Wnuk’s attack were Jewish, sources said. 

The three men were walking separately when Wnuk unleashed on them — punching one man in the back, another man in the shoulder, and another in the side of the head – all while screaming “f–king Jews,” according to sources.

All three victims complained of pain to their faces, but refused medical attention, according to authorities. 

Video taken of the immediate aftermath of the attack shows cops hauling away Wnuk – who’s seen sporting a black T-shirt with an image of the Iranian flag in the middle. 

Wnuk was arraigned in Brooklyn Criminal Court on the same day, where he was remanded with bail set at $5,000 cash, records show.

He is being charged with a bevy of crimes, including hate crime assault, according to court records. 

Wnuk’s attorney did not respond to The Post’s request for inquiry at time of publication. He’s is due back in court April 30.
