The head of Miami’s police union says the Ultra Music Festival should replace private security guards with city police officers.

In a proposal sent Wednesday to city commissioners, Miami Fraternal Order of Police President Javier Ortiz said security guards lack the training, experience and authority to handle crowds at the annual festival.

A guard was seriously injured after being trampled by gate-crashers at Ultra in March. City officials are considering whether to halt the three-day festival.

Ortiz also says concert-goers would be subject to pat-downs by officers, and he would prohibit duffel bags, cameras, computers, drugs, weapons and outside food and beverages.

Ultra recently hired the outgoing Miami Beach police chief as its new security director. An internal review of the festival’s security is pending.
