A young female security guard is fighting for her life, after being trampled by a mob at the Ultra Music Festival in Miami this weekend. 

The "Miami Herald" says 28-year-old Erica Mack is in "extremely critical" condition, after a group of unruly fans tore down the chain link fence she was standing behind in order to enter the venue without paying for tickets on Friday night. 

Police say reinforcements for the area had been called hours before the incident, but didn't arrive in time.  Miami's CBS 4 reports that Mayor Tomas Regalado says he will be prompting discussions on the city commission level about whether or not to allow Ultra permits for next year. 

The electronic music festival continued on as scheduled despite the tragedy.
