Statehouse workers were evacuated yesterday when a bomb threat was called into the Capitol around 2:40 p.m. Springfield police converged on the site along with bomb-sniffing dogs from Secretary of State Police. No bomb was found and the building was cleared for reentry at 5:19 p.m., according to Secretary of State spokesperson Dave Druker. The threat follows on the heels of 10 bomb threats made against area schools in recent months, although no connection has been established between the events.
