The Washington state Corrections Department says no one was injured when a small homemade bomb exploded Thursday afternoon outside the agency’s largest Pierce
County field office in Tacoma. A spokesman says the three-story building wasn’t damaged. Tacoma police are investigating. No threat was received before the device went off at about 3:30 p.m. The office was locked down until 5 p.m., when employees went home. The office will reopen today. Offenders report to community corrections officers at the field office.
