A female security guard at Ultra Music Festival was hospitalized on Friday after being trampled by a mob of people trying to barge through the gates and is said to be in “critical, yet stable” condition.

Erica Mack, a 28-year-old Contemporary Services Corporation guard, was brought to Jackson Memorial Hospital, after suffering from brain hemorrhaging and a broken leg, according to Billboard. As of Saturday night, she was in critical condition.

Mack was in charge of guarding a walkway on Friday night, when a mob of people without tickets forced their way in. They pushed down the fence and trampled over her.

“They saw an opportunity to try to get in without paying," said Lt. Ignatius Carroll, reports The Miami New Times. "There must have been a whole lot of people. We found her on the ground, screaming in pain.”

Ultra is a three-day music festival held at Bayfront Park in Downtown Miami. Over 160,000 are expected to be in attendance this weekend, which marks its 16th year.

According to CBS, 22 arrests were made on Friday and 26 on Saturday.
