Conor McGregor Arraigned Friday After Arrest; Next Court Date June 14

Conor McGregor was arraigned at a Brooklyn courthouse on Friday after he was charged with three counts of assault and one count of criminal mischief stemming from Thursday's bus attack at Barclays Center.

CBS News relayed video of McGregor and his defense attorney in court: 

According to MMA Fighting's Ariel Helwani, the Irishman reportedly agreed to have his next hearing on June 14 after posting $50,000 bail. He will be allowed to travel out of the country before returning for the second court date. 

Cian Cowley, who allegedly joined McGregor in attacking the bus, was charged with assault and criminal mischief, per Chelsia Rose Marcius, Christina Carrega and Thomas Tracy of the New York Daily News. He was ordered to post $25,000 bail. 

Thursday's chaotic scene unfolded following a press event for UFC 223 when McGregor and his entourage descended upon the loading dock at Barclays Center and targeted a vehicle carrying fighters who were scheduled to be on Saturday's card. 

Various videos show the group throwing a series of large metal objects at the bus, including a barricade and dollies: 

Helwani reported McGregor's group wanted "retaliation" because "Khabib Nurmagomedov and his team confronted Artem Lobov" earlier in the week. 

Several fighters suffered injuries, and three fights were subsequently canceled. 

According to MMAFighting.com's Dave Doyle, the preliminary between Ray Borg and Brandon Moreno was called off because Borg could not "close his eyes due to what he believed to be shards of glass from the incident."

UFC was also forced to cancel a lightweight showdown between Michael Chiesa and Anthony Pettis after Chiesa suffered several facial lacerations. 

Finally, the promotion pulled Lobov—who was allegedly part of McGregor's entourage on Thursday—from his featherweight fight with Alex Caceres.
