Earlier today a Harwich Resident brought an envelope to the public safety complex that contained a white powder.
The Harwich Fire Department requested a Tier 1 response (minor) from the Massachusetts HazMat Team to evaluate the substance.
After a thorough investigation it was determine that the substance was not harmful and that the letter had been a hoax or practical joke.
Residents are asked not to bring suspicious packages to the Police or Fire Stations, but to call 911 and have the packages investigated where they are found.
The Harwich Police assisted with the investigation.
