Conor McGregor goes crazy at UFC press conference, charged with assault, criminal mischief in Brooklyn bus attack

Cops charged UFC Conor McGregor early Friday for his role in an attack on a bus full of fighters at Brooklyn's Barclays Center.

The 29-year-old former UFC lightweight champ turned himself in at the 78th Precinct Stationhouse in Park Slope, Brooklyn, where he was slapped with three counts of assault and one count of criminal mischief, police said.

The UFC was forced to cancel many of the fights as a result of McGregor's actions. Some fighters were injured and declared unfit to fight on Saturday.
