A lot of terrible things can happen in a stadium’s cheap seats, and that is exactly what happened between the Chiefs and Broncos.

During the game at Arrowhead Stadium last Sunday, thousands of fans filled the stadium to see a great game between the AFC West rivals.

Unfortunately, some fans refuse to act like adults and behave like children when arguments break out.

One argument in the cheap seats was between one Chiefs fan and one Broncos fan. It would soon invlove a ton of people.

The video below shows stadium security in the area after a disturbance, but one Chiefs fan grabbed the Broncos fan above him and threw him and himself down several seats.

That Kansas City fan could then be heard yelling over and over, “I told you to f–king stop.”

Stadium security came in and broke them up, but the Denver fan became irate at one of them.

His anger caused one of his buddies to come over, punch security in the face, and push him to the ground.

Chiefs fans held down the Broncos fan who came down to attack security.

He was then likely arrested and taken to jail.
