Illinois Capitol Placed on Lockdown for About 2 Hours

The Illinois Capitol Building was on lockdown for about two hours Thursday afternoon as authorities investigated a "hazmat situation."

Capitol Police Sgt. Mike Moore says authorities were called because of the presence of an unknown substance.

City of Springfield Fire Marshal Chris Richmond says the powdery substance that prompted a hazardous material investigation at the Illinois Capitol was collected from several locations on the second floor, including the governor's office.

He says a preliminary analysis shows the substance wasn't hazardous, which prompted authorities to reopen the building after Thursday's roughly two-hour lockdown.
 
Dave Druker, a spokesman for the secretary of state's office, which oversees Capitol security, says one person is in custody in connection with the incident.

No injuries were reported but no one was allowed to enter or exit the building for about two hours.
