MIAMI -

Organizers of Miami's Ultra Music Festival are hiring the outgoing Miami Beach police chief to oversee security after a guard was trampled by gate-crashers.

Ultra producers announced Friday that retiring Chief Ray Martinez will help the 14-year-old dance music event strengthen security in future years.

Martinez has more than 35 years of law enforcement experience including supervising security at events such as Art Basel and Memorial Day weekend.

"Chief Martinez has built a record of distinguished service in law enforcement and we are honored to have his insight and leadership as part of the Ultra team," Russell Faibisch, founder of Event Entertainment Group Inc., which produces Ultra, said in a statement. "The safety of our event, fans, crew and personnel has always been our No. 1 concern."

The festival at Miami's downtown Bayfront Park has been scrutinized by city leaders after Ericka Mack was trampled. She suffered a broken leg and serious head injury March 29 and released from Jackson Memorial Hospital last week.

Miami officials are considering whether to halt the festival, which has grown larger and rowdier. Festival producers are conducting a complete security review.
