Teenager Joshua Prater, was arrested after his housekeeper found an explosive device in his room while she was cleaning, according to police.
According to azdamily.com, after the housekeeper brought the device to the Tempe (Arizona) Fire Department, a bomb squad examined it and discovered it to be an active improvised explosive device. Tempe Police Sgt. Mike Pooley told MyFoxPhoenix.com, "They had it X-rayed, they saw it was a valid IED." He added, "It was something that wasn't big, but could cause serious injuries and the death of someone."
Pooley also said, "There was fuse that was coming out from the device which would be how you light it and it would cause the fuse to go in there and explode," Pooley said. "The bomb was ready to go. It was active. All it needed was the trigger."
The bomb was diffused by the bomb squad and investigated the 18-year-old's home and found more home made bomb materials. Authorities later charged Prater with misconduct involving weapons and possessing a prohibited weapon.
