A United Airlines worker and a passenger took swings at each other in a bloody brawl captured on a Newark Airport check-in station.
Video of the fight at the New Jersey airport was shared on Twitter just before 9: 30 a.m. Sunday.
Footage shows a man wearing a dark blue hooded sweatshirt have an argument with an airline worker wearing a dark vest when the man in the vest strikes the other man in the face.
The man in the sweatshirt responds, You saw that s - -! The video shows that the worker punches the worker in the face twice, knocking him to the ground.
When the man in the vest stands up, he is seen bleeding from his head. He confronts the other man again and they continue to argue. Another airport worker appears to step in as the video ends.
What happened before the camera started rolling wasn't immediately clear.
A airline spokesman told WPIX-TV in an emailed statement that the man in the vest works for a subsidiary company affiliated with the airline and was not taken into custody.
The man in the hooded sweatshirt was taken into custody, according to the spokesperson. He was not sure whether he would face charges.
