According to TMZ, a witness on the plane said Tyson earlier had taken a selfie with a couple of passengers and was patient with one overly-excited passenger who kept trying to talk to Tyson as he sat behind the 55-year-old former heavyweight fighter.

The report cited sources close to Tyson as saying the man was extremely intoxicated and wouldn’t stop provoking the boxer while in his seat.
