MIAMI (AP) - 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 over 35 years of law enforcement experience including supervising security at events such as Art Basel and Memorial Day weekend.

The festival at Miami's downtown Bayfront Park has come under fire following the trampling of guard Ericka Mack, who suffered a broken leg and serious head injury on March 29. She was released from the hospital last week.

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