An arrest warrant has reportedly been issued for Conor McGregor after the Irish fighter attacked a coach carrying numerous UFC fighters at the Barclays Centre in New York.

McGregor, who was stripped of his lightweight championship title this week, gatecrashed a media event ahead of this Saturday’s UFC 223 where he was filmed picking up railing before attempting to throw it at the coach.

Inside the vehicle was Khabib Nurmagomedov and other UFC fighters on the way back to their hotel from the Barclays Centre. Lightweight Michael Chiesa is reported to have suffered a cut to his forehead during the incident. 

"Conor went bananas and put a beating on the van that we were in looking for Khabib. "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 it's too serious." Chiesa's coach Rick Little told MMA Junkie. 

He added, "Everything happened so fast, it was just like we were jumped."

UFC president Dana White said that a warrant for McGregor's arrest had subsequently been issued.

"There is a warrant out for McGregor's arrest. They're looking for him right now and his plane is grounded. I assume if they don't catch him he will turn himself in. He's going to be sued beyond belief and this is a very bad career move for him."

Take it for what you will, but McGregor has been rumored to make a surprise appearance at WrestleMania 34 in New Orleans on Sunday, although one would have to imagine WWE would play cautiously right now given the bad publicity it could potentially bring them.
