EDM event charged with negligence over weak fencing.

The security guard who was trampled by gatecrashers at this year’s Ultra Music Festival has filed a $10 million lawsuit against her former employer.

Erica Mack sustained two skull fractures, bleeding in her brain and from her ear, and a leg broken in three places when gatecrashers knocked down the chain-link fencing she was standing nearby at the perimeter of the Miami festival.

Mack’s complaint rests on an agreement between the city and Ultra that the festival would use sturdier ‘G8’ fencing in weak spots around the event area, and that the area Mack was deployed had been identified as being “particularly vulnerable to gatecrashers.”

“All they had to do was follow through with what they promised. One of the things they were obligated to submit was a security plan which showed G8 fencing around the perimeter,” said Mack’s attorney. “This was easily preventable, without a huge expenditure. They could’ve gotten this thing to where it was safe, and they didn’t.”

The suit has been filed against Ultra and its parent company Event Entertainment Group, as well as the city of Miami, the management organisation in charge of the park where the event was held, the security and concessions companies for the festival and the fencing company.

Ultra responded to the allegations last week in a statement, saying: “The safety of our event, fans, crew and personnel has always been our number one concern. Despite our best efforts to continue to provide a safe and enjoyable event for our patrons and staff, certain criminal acts will always be beyond our control even though we continue to assure that security is of prime importance.”

It’s not the first time the festival has been accused of negligence regarding safety – two workers were injured at last year’s Ultra when a 7ft high mounted LED screen partially collapsed on stage. [via Billboard]
