The chaos did not end with the entrance breach either.
Multiple fans were trampled as hundreds rushed the event's perimeter Friday afternoon. Once inside, some people began climbing onto portable toilets as security personnel worked to try and contain the crowd.

Event-goers erupted into a mad rush at a secured entrance to the venue, stepping onto each other as they made their way inside.
ABC13 Reporter Mycah Hatfield was near the entrance as the mob approached, and said security personnel were able to move some people away from the entrance before the crowd overtook the gates.
One person who was detained by security talked to ABC13.
"I just really wanted to be inside the festival so bad," he said.
Of those who were trampled during the rush, there was no word on how many people were injured, but none appeared to be severe.
The crowd disregarded metal detectors and security guards who were checking bags.
Members of the Houston Police Department's Mounted Patrol Unit were also on scene and worked to contain the chaotic scene.
The event's 100,000 tickets sold out within an hour of going on sale back in May.
Travis Scott, the popular rapper and organizer, launched the Astroworld Festival in 2018. Like most other large events, it was canceled in 2020 due to the COVID-19 pandemic.
