Andrew Waller faces charges of possessing an explosive device and possession of methamphetamine with intent to deliver. The Pekin Daily Times reports the pipe bomb was powerful enough to blow shrapnel into a house and kill residents.
It is unclear why Waller had the bomb or what he intended to do with it.
The safe was seized after Waller was pulled over in an early Thursday traffic stop. The safe was taken back to the city hall building, which also houses the police department. When police later obtained a warrant to open the safe, the bomb was discovered inside.
The city hall building was evacuated around 10:15 a.m. Thursday. The Peoria Police Department's bomb squad was called in to detonate the bomb remotely with a robot. Nobody was harmed in the incident, and city workers were allowed to return shortly after noon.
