The NYPD was hunting for MMA star Conor McGregor on Thursday after he went on a rampage at Barclays Center and allegedly injured another fighter, police sources told The Post.

Cops wanted to question the Irish UFC champ on suspicion of assault and criminal mischief for the post-press conference fracas — although they were also suspicious that it was a “publicity stunt” ahead of UFC 223 on Saturday, sources said.

McGregor and his team showed up to the arena at the end of a press conference looking for a fight with UFC lightweight contender Khabib Nurmagomedov — but fellow fighter Michael Chiesa is the one who ended up hurt when McGregor allegedly hurled a hand truck through the window of a van, sources said.

“Conor went bananas and put a beating on the van that we were in looking for Khabib,” Chiesa’s coach Rick Little told MMAJunkie. “A million security guards had to restrain him. Mike’s cut up now. He’s got marks on him, for sure. I don’t think too serious. Everything happened so fast, it was just like we got jumped.”

Video posted by TMZ appears to show McGregor in the arena’s parking garage, hurling the dolly at the van and smashing its front window.

Warning: Graphic language

In another video posted by UFC fighter Felice Herrig, McGregor can also be seen throwing a metal barrier and metal garbage can around the lot.

Afterward, McGregor and his entourage left Barclays and jumped into a waiting SUV, footage posted on Instagram by a Las Vegas Review-Journal reporter shows.

The FDNY confirmed one victim was transported from the scene to Methodist Hospital at 1:39 p.m. with a possible head wound.

Artem Lobov, McGregor’s close friend, has been pulled from Saturday’s fight, UFC President Dana White told reporters, labeling the entire incident as “disgusting”

“After this disgusting, despicable move, I think everybody’s relationship with Conor’s gonna be not so great,” White said.

“Not a great career move.”

The melee comes a day after White announced that he was stripping McGregor of his lightweight championship belt and awarding it to the winner of this weekend’s fight between Nurmagomedov and Max Holloway.

But McGregor and Nurmagomedov have a rivalry that stretches all the way back to UFC 205 in 2016.

After he won his match early in the evening, Nurmagomedov took the mic and called McGregor a “chicken.” The moniker stuck and McGregor even poked fun at it in a recent commercial for Burger King’s newest chicken sandwich.

However, the relationship turned into more than banter Wednesday. Running into each other in the fighters’ hotel, Nurmagomedov got into a verbal altercation with Lobov.

“Never say my name. You got me? I didn’t hear you?! Motherf—-r,” Lobov apparently said.

“You didn’t say it? You didn’t say it? Don’t say these things again. Chechen man.”
