Envelope forces extended lockdown at Hendersonville Police Department

Posted: Updated:
HENDERSONVILLE, Tenn. -

The Hendersonville Police Department headquarters on Executive Park Drive was on lockdown Thursday after an envelope containing a white, powdery substance was brought to the station.

Authorities stated that around 12:30 p.m. a local couple went to the police station to report a threatening letter they received at their home.

Police said the envelope they brought in contained a suspicious white powder, causing a quarantine of the department.

Thirty two employees were present at the time of the lockdown.  They remained inside the building until the environment was deemed safe around 8:30 p.m.

Initial tests showed that the white substance was not a hazardous or weaponized material.  Authorities said the material contained a small amount of boric acid, which is classified as a dangerous substance.

Officials added the threat is limited to the couple who received the letter.  There are no signs of anyone else being targeted.

The police department continued operating as normal throughout the lockdown, but roll call for night shift employees was held outside.

The department's headquarters are expected to be open for normal business hours Friday.

An investigation into the identity of the letter's sender is underway.

Police urge anyone exposed to suspicious, unknown materials to leave it where it is and slowly walk away.
