UFC fighter Conor McGregor was arraigned in Brooklyn Criminal Court on Friday after he and his entourage attacked a bus carrying other MMA fighters on Thursday evening, according to the BBC. The former lightweight champion, who was charged with multiple counts of assault and one count of criminal mischief, was released on $50,000 bail, after spending the night in jail. He's still allowed to travel between Ireland and the United States as the case proceeds. McGregor, a day after he was stripped of his lightweight championship title due to inactivity, went on a rampage Thursday evening at the Barclays Center in Brooklyn, throwing chairs and dollies at a bus taking rival fighters away from a press conference. He eventually hurled a hand truck at a bus window. Two fighters were injured in the melee, and their Saturday fights had to be canceled. Cian Cowley, another fighter involved in the incident, was charged with assault and criminal mischief, and posted $25,000 bail.
