New York Black Lives Matter founder Hawk Newsome ranted about “black faces of systemic oppression” as he turned himself in Monday to face charges for allegedly assaulting a black local leader during a dust-up at a political rally in Harlem last week.

The activist is accused of punching Manhattan Democratic District Leader William Allen, 66, and hurling a bullhorn at him when the protest descended into chaos at about 10:45 a.m. on Friday, according to police and sources.

The entire saga unfolded when Newsome and a host of activists swarmed the Harlem office of Councilman Yusef Salaam — one of the exonerated Central Park Five — to object to non-profit leader Tiffany Fulton having $10,000 in her community funding pulled.

The scuffle broke out after Salaam’s mother, Sharonne – on hand for a separate press conference — went over to confront Newsome, who was shouting her son’s name into the bullhorn during the rally,  Allen said in an interview Monday afternoon.

Allen, who was there for the other press conference on solitary confinement, described himself as an “innocent bystander” – telling The Post he walked over at the same time to chat with Fulton, but ended up facing the ire of Newsome. 

Video footage circulating online shows Newsome getting in Allen’s face and accuse him of bringing an “old lady over here” in reference to the councilman’s mother.

“My problem is with you ‘cause I can’t get in her face like that,” he yelled as he appeared to let the bullhorn go, according to the footage.

“You put an old lady in front of me,” he also screamed even though Allen claimed Sharonne walked over on her own.

“He basically assaulted me,” said Allen. “He hit me in the chest, I backed up and as I’m backing up he raised his arm and threw the bullhorn at my head. Thank God it missed me.”

The prominent local leader said he then faced the wrath of a Newsome ally who complained when the NYPD got involved while Newsome refused to offer an apology.

“He never did that, and that was it for me,” he said. “Had he done that, I probably would’ve never taken the trip over to the [precinct].”

Newsome, who urged supporters to gather outside the 28th precinct to watch as he voluntarily surrendered first thing Monday, compared himself to Martin Luther King Jr. as he decried the looming charges as politically motivated.

“Recognize this as a step in the right direction. Not only do we fight racism — systemic, black racism — we fight the black faces of systemic oppression,” he said.

“Martin Luther King Jr. got locked up 26 times. Right? 26 times for this. This is a sign that we are fighting,” Newsome continued.

Allen shot back, “I may not have known Dr. King personally, but he’s no Dr. King.”

Newsome was charged with attempted felony assault, attempted misdemeanor assault and harassment, cops said.

“The charges against me are false,” the BLM leader insisted.

“This person is saying that I hit him, but there’s no video evidence of that. There’s 30 cameras out there. Nobody has a video of that. The only thing that was hurt was his pride.”

As Newsome was being led out of the police precinct, he argued he was the victim of “a political attack.”

“I’m not even thinking about the charges. I’m thinking about Al Sharpton, Yusuf Salam, using the same justice system that they promised to fight against, against me.”

Newsome’s allies, too, were quick to claim the charges were “trumped-up” and “politically motivated.”

Fulton, the executive director of Silent Voices United Inc. who recently had her funding cut, accused others of inciting disruption and chaos.

“To see this kind of political weaponization in Harlem is heartbreaking,” Fulton said in a statement.

“We are witnessing firsthand how speaking truth to power comes with consequences when the system feels threatened,” she continued.

“When people incite chaos and then hide behind police badges and political titles, it shows how far some will go to protect lies.

“The domino effect of ignorance, gossip, and misinformation is real — it destroys good people while the guilty hide behind power.”

Her organization had $10,000 pegged for its coffers, according to paperwork shared on Instagram by her non-profit Silent Voices United.

Allen, the Democratic leader who has a prior working relationship with Fulton, is shocked how quickly things descended into chaos.

“In Harlem, we’re a village,” he said. “We have differences, we are able to work out differences.”
