The people who stormed the fence at Southeast 1st Street and Biscayne Boulevard were trying to crash the event since they did not have tickets, according to our news partners the Miami Herald.

Jessica Schulyer said she feels relatively safe inside the gates of Ultra, but she’s concerned after hearing what happened to the security guard.

“If it could happen to her, it could happen to me,” said Schulyer.

City of Miami Comissioner Marc Sarnoff said the situation could have been predicted and prevented and he is calling for answers, investigations, and an end to Ultra in Miami.

“It was so predictable that stampede situations would happen. We came up with five different scenarios. I challenged risk and all they kept on saying was, ‘Commissioner, what do you want us to do?’ There was a sort of stampede of people who were trying to get in, very much like what happened last year, but it was about 500 people last year,” said Sarnoff. “They tried to get into the front gate last year and we had enough security from the City of Miami Police Department. They put their bikes across their chest and they pushed back and they were able to hold the people back. I’m asking the Chief and the Chief of Fire to meet with me, the Mayor, and the Miami-Dade County Mayor. Let’s get through this weekend and put this thing to bed, never come back again.”

Paramedics responded to about 50 rescue calls on Friday and took more than a dozen people to the hospital.
