The entire Sioux City Community School District was placed on lockdown this (Wednesday) morning after a threatening call was received around 8:20 a-m at the administration building. Sergeant Brad Bollinger of the Sioux City Police says the call claimed that explosive devices had been placed at each school in the district, and that the schools would be attacked with rifles within a half hour.
Officers were dispatched to the buildings and the call proved to be a hoax. Bishop Heelan High School Principal Chris Bork says the city parochial schools did not receive the call, but police notified them of the threat and they also briefly went on lockdown.
The lockdown was canceled at 9:15. Sergeant Bollinger says the F-B-I has been notified of the threat and the investigation is continuing.
