TEMPE, Ariz. -- Tempe police released photos taken inside the home of a high school student accused of making an improvised explosive device.
Joshua Prater, 18, a senior at Marcos de Niza High School, was arrested on May 7.
A cleaning woman found a device that looked like a bomb in Prater's home and took it to a Tempe fire station to have it checked. Police were called and a bomb squad disabled the device.
The woman told police that there were more materials in the home near McClintock Drive and Baseline Road. Police searched the residence and found six small white canisters, jars, tape, gun powder and a CO2 cylinder.
Prater told police that he made the device about eight years ago. According to court documents, Prater said he didn't know the device was filled with explosive powder, along with match heads and fireworks.
Police said Prater did not make any threats toward his school.
Prater is accused of one count of misconduct involving weapons, a felony. He is out of jail on bond.
