TUCSON (KGUN9-TV) - Tucson Police are investigating at least 13 bombs threats made in the last week at buildings across town, including schools and government buildings.
The latest threats were made at five school buildings in four different Tucson districts: Palo Verde (TUSD), Amphitheater High School, Desert View and Sunnyside High Schools, and the Flowing Wells Administration Center.
Tucson Police said the threatening calls all came in around 2:30p.m. Tuesday.
Amphitheater, Desert View and Sunnyside evacuated, but classes were already out or about to be let out by the time the calls came in.
The threats to the school buildings are the latest in a string of bomb threats in Tucson that began the day of terrorists attacks in Brussels, Belgium.
The first day, March 22, threats were phoned-in to four places, including the Pima County Attorney's Office and IRS building downtown. Two days later, four more businesses around town received bomb threats.
No suspects have been accused of making any of the threats. Sgt. Pete Dugan with the Tucson Police Department said they can face charges of "hoax," "terrorism," or "interfering with an educational facility." All of those are felonies.
