2ND UPDATE wth charges filed: UFC fighter Conor McGregor has been criminally charged in connection with Thursday’s brawl at the Barclays Center in Brooklyn.

McGregor, who attacked a van carrying rival fighters after a press conference at the arena ahead of Saturday’s UFC 223 card, was charged with felony criminal mischief and misdemeanor counts of assault, attempted assault, menacing and reckless endangerment. He faces as much as seven years in prison if convicted on all charges.

An order of protection was issued against McGregor that bars him from contacting fighters Michael Chiesa and Raymond Borg, who were hit with flying glass when McGregor threw a dolly at the van. Borg sustained a cornea abrasion and facial bruising, while Chiesa had cuts to the hand and face. Both had bouts scheduled for the UFC’s Saturday showcase at Barclays, but both fights are now canceled.

McGregor is also accused of hitting fighter Jason Ledbetter in the head with a closed fist. He also received an order of protection against McGregor.

McGregor posted $50,000 bail. The 29-year-old Irish fighter must return to court on June 14.

UPDATED, Thursday PM: Conor McGregor turned himself in to the police in New York City Thursday night after a brawl at Barclays Center earlier in the day.

The UFC champ is currently being “detained” for questioning. Police sought him after the incident, which resulted in a head injury to one of the participants.

Police Officer George Tsourovakas said late Thursday that McGregor has not been formally charged. “The investigation is continuing,” he said.

McGregor and his posse were apparently enraged by the presence of UFC lightweight contender Khabib Nurmagomedov, who was at the arena for a press conference touting an upcoming fight, UFC 223, set for Saturday.

At the end of the press conference, Nurmagomedov was exiting when McGregor and friends attacked them. The NYPD are now looking to question the Irish UFC champ, who potentially could be charged with assault and criminal mischief.

McGregor is best known for his battle last year with boxer Floyd Mayweather, a brief transition to boxing for McGregor that earned him an estimated $30 million to $75 million (Mayweather, the bout’s winner, scored an estimated $100 million).

The stakes were a lot less on Thursday at the Barclays Center

“Conor went bananas and put a beating on the van that we were in looking for Khabib,” said fighter Michael Chiesa’s coach, Rick Little, to the MMAJunkie blog. “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.”

A video on the scene shows McGregor hurling a dolly at a van and smashing one of its front windows. McGregor was also captured throwing a metal barrier and metal garbage can around the lot.

The incident resulted in one victim being taken to the hospital with a head wound.

McGregor has a rivalry with Nurmagomedov that goes back to UFC 205 in 2016. But the fight also comes a day after the UFC head said 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.

Some cynics – including, reportedly, the police – believe the incident may have been part of pre-fight hype.
