A housekeeper finds a bomb in the bedroom of a Marcos De Niza High School senior. Joshua Prater, 18, was taken into custody on suspicion of misconduct involving weapons and possessing a prohibited weapon.
The woman took the device to a Tempe Fire Station to have it checked out about 2:30 p.m., police said.
Firefighters immediately notified Tempe police, who responded to the scene and deemed the device as a legitimate IED, which was disabled.
The woman told police that there were more materials in Prater’s bedroom at the house she was cleaning. She had taken photos of the materials, which showed items used for making more IEDs.
Police were searching the house Tuesday evening.
Police haven’t found any threats to Prater’s school but have taken precautionary measures by notifying officials there. Police also plan to check the school for any threats.
Prater lives with his mother and father, who were interviewed by police cleared of any involvement.
