Powder leads to lock down at DSM federal building

Posted:

DES MOINES (AP) - A suspicious powder found at the federal building in downtown Des Moines has turned out to be harmless.

Police blocked a street that runs in front of the building so hazardous material crews could investigate a report Monday of a suspicious package after someone in the mailroom opened an envelope with a white powder inside.

Des Moines Fire Inspector Ted Jefferson says the 10th floor of the building was also shut down but reopened early Monday afternoon.

Jefferson says the powder turned out to be a common substance but did not elaborate.
