Watch the moment McGregor aims metal railing at Nurmagomedov's bus in New York after being stripped of belt as UFC claim a warrant for his arrest has been issued

                                                                                    Conor McGregor (inset) is not on the UFC 223 fight card in Brooklyn on Saturday, but the mixed martial arts superstar still made headlines at Thursday's media day by attacking a bus full of rival MMA fighters and leaving them 

covered in shattered glass. Police and EMS were called according to UFC president Dana White, who said that there is a warrant out for McGregor's arrest. However, an NYPD spokesman would not confirm that there is a warrant 

for McGregor's arrest, instead saying that the investigation is ongoing. The Irishman was slated to be cage-side for teammate Artem Lobov's fight before Khabib Nurmagomedov and Max Holloway square off for the lightweight belt 

McGregor is scheduled to lose on Saturday. White previously ruled that McGregor would have to forfeit the belt to whomever won Saturday's title bout because the 29-year-old has not participated in a UFC event since 2016 - nearly a 

year before his doomed boxing debut against Floyd Mayweather Jr. in August of 2017.. The skirmish occurred as Nurmagomedov made his exit from the arena's bottom floor. As the lightweight's bus inched towards the truck elevator, 

McGregor and his posse attempted to climb aboard before one of the windows got smashed, leaving the passengers covered in glass. UFC lightweight Michael Chiesa suffered a laceration to his face and one UFC employee broke a knuckle, according to White.
