On Friday, mixed-martial-artist Conor McGregor was in custody in New York on charges of assault and criminal mischief after a van-smashing incident at a UFC press event in Brooklyn that was caught on video. McGregor turned himself in to police late on Thursday after the violent incident at the Barclays Center in Brooklyn. Lee Jones, an NYPD spokesman, said that the 29 year-old McGregor was due to be transferred to the criminal court in Brooklyn for an arraignment hearing later on Friday.
