The Notorious Conor McGregor flew by private jet from Ireland to appear at a Brooklyn court today.

Mixed martial arts fighter Conor McGregor is in plea negotiations to resolve charges stemming from a high profile meltdown at Barclay's Center earlier this year.

The Irishman and co-defendant Cian Cowley appeared in court this morning in Brooklyn.

According to reports, the men are due back in court on July 26th.

Assistant District Attorney Janet Gleeson told the court that the case hasn’t yet been presented to a grand jury for possible indictment because of the ongoing plea negotiations.

“I regret my actions that led me here today,” the 29-year-old sports star.

“I understand the seriousness of this matter and I’m hopeful to get it resolved soon.”

The incident in question involved a melee between McGregor, his entourage, and other UFC stars. 

Videos footage showed the dad-of-one hurling a hand truck at a bus filled with rival fighters after a news conference for the UFC 223 event at Barclays Center in April.

The incident left two fighters injured by broken glass and unable to compete.
