Mike Tyson was seen punching a man multiple times on a plane Wednesday night, leaving the victim bloodied.
The video appeared to show Tyson hitting the man, who was seated behind him. The incident happened at the San Francisco International Airport. The flight was about to leave for Florida.
A witness, who is the victim's friend, said that Tyson was initially friendly and even took a selfies with them, but when his friend didn't heed Tyson's warning to stop bothering him, the former pugilist lashed out physically.
The witness said Tyson walked off the plane and the man went to the police.
One of the most famous and successful fighters of all time is Tyson. He won each of his first 37 professional fights and retired with a career record of 50 victories, including 44 knockouts.
Tyson has been in trouble outside of the ring before. He was sentenced to three years in prison after being convicted of rape.
He bit Evander Holyfield's ear during a 1997 fight.
Tyson will return to the ring in 2020 for an exhibition fight against Roy Jones Jr., which was scored a split draw.
