Conor McGregor, mixed martial arts fighter, has been charged with assault and criminal mischief by New York City Police Department, NYPD. The 29-year-old was among a group of men alleged to have vandalised a bus containing rival fighters, the Ultimate Fighting Championship, UFC has said.
The Irishman turned himself into police custody at 9pm local time on Thursday. NYPD told BBC Sport that McGregor will see a judge after 7am (12pm BST).
The incident occurred at Brooklyn's Barclays Center, where the UFC had gathered to promote Saturday's show, headlined by Khabib Nurmagomedov and Max Holloway. McGregor was with fellow fighter Artem Lobov, who was due to fight featherweight Alex Caceres.
The UFC says McGregor and Lobov - accompanied by more than a "dozen individuals" - attacked the bus. Footage appears to show McGregor throwing a trolley at the bus - smashing a window - followed by further altercations.
UFC says two fighters were injured and have been withdrawn from Saturday's undercard.
Lightweight Michael Chiesa received several facial cuts, while flyweight Ray Borg suffered an eye injury. Lobov has also been removed from the bill, due to his alleged involvement.
McGregor, who was beaten by Floyd Mayweather in a boxing match in August 2017, has not fought in the UFC since knocking out Eddie Alvarez in November 2016. Before Thursday's incident, he was stripped of his UFC lightweight title.
