Suspicious white powder found in an envelope was determined to be non-hazardous Monday afternoon at the Northeast King County Courthouse in Redmond.

According to Becky Range, Redmond Police Department (RPD) public information officer, at around 2 p.m., the courthouse at 8601 160th Ave. N.E. was evacuated when a worker opened the envelope that was sent to the courthouse.

RPD assisted with the evacuation, secured the building and Redmond Fire Department responded inside the facility. A United States Postal Inspection Service (USPIS) inspector quickly arrived on scene, completed an evaluation and removed the package from the courthouse.

Earlier in the day, a similar envelope containing white powder was also sent to the Issaquah courthouse and opened by an employee; it was also determined to be non-hazardous.

USPIS is investigating the incidents.
