PHOENIX — The downtown Phoenix offices of Sheriff Joe Arpaio were temporarily evacuated Monday morning because of a suspicious envelope addressed to the sheriff containing a white, powdery substance.
A spokesman refused to release details to The Associated Press until an afternoon news conference.
The Arizona Republic reports the envelope was opened on the 19th floor of the Wells Fargo building where the sheriff's office has its headquarters. The unknown substance was found inside the envelope.
A Phoenix Fire Department hazardous materials crew responded.
The crew removed the envelope, and people working in the area were allowed to return.
Officials were still investigating. No injuries were reported.
