The devices were reported at about 8:30 a.m. outside of a Del Taco on State College Boulevard, just south of Chapman Avenue. A restaurant employee found the devices. Del Taco and other surrounding businesses were evacuated.
Nearby Cal State Fullerton was not placed on lockdown, but Troy High School was placed on modified lockdown. The school's assistant principal said students were not allowed on athletic fields as a precaution, but everything else was running as normal.
Bomb squad officials said one of the devices looked like a pressure cooker with wires. By around noon, all three devices were rendered safe. The Fullerton Police and Fire departments and the Orange County Sheriff's Department were conducting a joint investigation. Authorities said they would conduct a walk-through before lifting the evacuation and letting people back in.
