White powder accompanied by threatening notes prompted evacuations at three downtown Denver buildings housing state agencies Monday, while a powdery substance at a suburban building forced the evacuation of a state police call center.

An envelope sent to the state Department of Natural Resources near the State Capitol contained sugar and one sent to the World Trade Center contained a sugar substitute. Another envelope sent to the building housing the Department of Regulatory Agencies also contained a sugar substitute.
In Lakewood, an employee opening a letter sent to the state Department of Agriculture came into contact with a powder. That forced the evacuation of the four-story building that houses several state agencies, including the state patrol's Denver dispatch center.
