The passenger was arrested, not the employee, according to law enforcement. An airline passenger and a United Airlines worker got into a fight at Newark Liberty International Airport, and the worker ended up flat on his ass. The witnesses say the 2 began arguing before punching each other. The worker seems to push the passenger, who slaps the employee in the face, and then all hell breaks loose. The blows clearly landed when the passenger threw punch after punch after the 2 square off, because the employee fell behind the counter. The craziest part is when the employee comes back for more, but he is clearly sleepy and bloodiest. In the video, the passenger says that the employee started the fight and that he doesn't start it. We contacted the airport police to find out if anyone had been arrested. Originally published at 6:40 AM.
