A 28-year-old security guard who was trampled by concertgoers at the Ultra Music Festival Friday is in critical condition. According to sources, the female guard was crushed by gatecrashing a--holes who broke through a chainlink fence at the annual Miami EDM bash.

Erica Mack suffered severe brain haemorrhaging and a broken leg after the incident, which took place around 9.30PM as fans tried to get into the fest for free.

According to a Miami Fire Rescue spokesperson, "Erica was doing what she was supposed to do, telling them to stop. They just trampled her.” Nearly 50 people have been arrested on Friday and Saturday for crashing into the grounds.

The security guard is listed in stable but critical condition. A fan posted a photo on Twitter following the incident Friday night:
