BLOUNT COUNTY, Tenn. (WVLT) -- Three Blount County corrections officers were taken to the hospital after finding a suspicious letter, containing a white powdery substance at the jail around 9:30 Thursday morning.
The Maryville Police Department responded to the scene and decontaminated the area where the letter was opened.
The Joint Terrorism Task Force will test the substance in a lab.
The corrections officers were treated at Blount Memorial Hospital as a precaution and released.
The matter is now under investigation.
Policy was already in place for a “postcards only” inmate mail system beginning February 1st, with the exception of legal mail. The Sheriff's Department says the new policy will keep this type of incident from happening.
