The building containing Pekin’s City Hall and Police Department headquarters was evacuated for two hours late Thursday morning after a pipe bomb was found in a safe confiscated from a man arrested the night before.

The device was detonated at about noon by members of the Peoria Police Department’s Bomb Squad, sending a shotgun-like blast reverberating through the downtown area.

No one was injured in the event.

“You want to think nothing like this would happen here, but it does,” Mayor John McCabe said as he stood outside police headquarters at 100 S. Capitol St.

“There are highly qualified, professional people who know what they’re doing” in handling the apparent explosive, McCabe said several minutes before it was detonated in the department’s parking lot. The area had been cordoned off with police tape during the evacuation.

Police Deputy Chief Don Baxter said the bomb was found in a safe that police found in the vehicle of a man they arrested during a traffic stop Wednesday night.

“The suspect refused access to the safe, so we obtained a warrant” to open it, he said.

When it was opened at about 10:15 a.m., the bomb was discovered and the building was immediately evacuated.

The Peoria department’s bomb squad was unable to open the cap sealing the device, said Public Information Officer Billie Ingles. Plans were then made to detonate the device. A loud buzzer was sounded one minute before detonation took place.

Police confirmed the device indeed was a bomb when it was detonated, Ingles said.

Employees at City Hall and police headquarters were permitted to reenter their adjacent offices 10 minutes after the bomb was detonated.

Baxter said the man who possessed the safe was questioned by investigators after the device was discovered.

The arrested man was booked into jail on a charge of possessing methamphetamine. He would not be identified Thursday while the bomb-related investigation continued, Ingles said. Formal charges related to his drug-related arrest also had not yet been filed.
