The State Capitol building in Madison, Wisconsin, was evacuated Wednesday afternoon due to a "credible bomb threat."
FOX 6 reports that the evacuation began just before 4 p.m., when legislators were debating the state's budget in the building's Assembly Chambers.
Authorities told people to get on the other side of the street of the building, with those gathered on the Capitol lawn for an evening music concert also moved.
Lawmakers and other Capitol staff were allowed back in shortly after 5.30 p.m. after police gave the building "the all clear."
"Due to a credible bomb threat, we are evacuating the State Capitol," administration department spokesman Cullen Werwie said when the evacuation was announced, according to the Fargo Forum.
Gawkers notes that the threat was reportedly made against the building, rather than an individual.
