PHOENIX (AP) -- Maricopa County officials say a 60-year-old inmate in Sheriff Joe Arpaio's tent city has died from cardiac arrest.

Authorities say Arthur Madril died Saturday after he was found by detention officers.

Officials say officers immediately performed CPR. Phoenix firefighters arrived and later pronounced Madril dead.

Authorities believe that Madril died of natural causes but an investigation has been launched into his death.

Madril was behind bars on a $4,000 child support warrant, and was on work release.
