Police cordoned off a South Seattle street Monday afternoon and called in a SWAT team, bomb squad, and fire department hazardous material crew after a group of cleaning workers were sickened by a white powder in a booby-trapped foreclosed home.

According to two police sources, a group of workers entered the foreclosed home on 32nd Ave. S. and S. Edmunds near Columbia City Friday and found booby traps, a white powder, and "threatening literature."

Police say the cleaners did not contact police about the incident until 1:00 pm Monday.

Police have shut down streets around the home.

We'll have more info as it becomes available.

Update: Seattle police say detectives have cleard the home and "all suspicious items have been determined to be harmless."
