CHANDLER, Arizona - Police in Chandler, Arizona evacuated a school Tuesday morning after a student received a text message from a 16-year-old schoolmate threatening a "Columbine-type" incident, reports CBS affiliate KPHO.
Officers said they found two suspicious packages, one inside and one outside Ken "Chief" Hill Learning Academy, an alternative school for junior high and high school students, Chandler police Detective Seth Tyler told the station.
Chandler police say it's still unknown what the packages contain and if they're explosive.
The teen was taken into custody at an apartment complex where a possible explosive device also was located, leading to a partial evacuation of the complex.
Police say a student told the school's principal that another student was threatening the school and allegedly had something planned at 11:25 a.m. Tuesday.
Police say the academy was evacuated and authorities now are checking cars in the school's parking lot for possible explosive devices.
