RUTHERFORD COUNTY, Tenn. (WKRN) — A block of downtown Murfreesboro was evacuated Friday morning after a report of a suspicious device inside the Republican Party of Rutherford County building, county officials say.

Several agencies responded around 9:30 a.m. to the call of a device located at the building on East Main Street between South Church Street and South Spring Street.

The Tennessee Republican Party released a picture of what looked like a bomb in a box with a note that read: “This is just a warning, there will be no others. There will be no unconstitutional gun control in this state, or there will be blood.”

Rutherford County Emergency Management told News 2 the bomb squad was dispatched to the location.

Rutherford County Republican Party chairman Daniel Gammon released a statement following the threat:

This morning we received a package at the Rutherford County Republican Party headquarters that appeared to be a bomb. We immediately contacted local authorities and evacuated the building. We are thankful for the quick action of Murfreesboro law enforcement and that all of our volunteers and staff are safe.

Tennessee Republican Party Chairman Scott Golden also released a statement:

The threat made against the Rutherford County Republican Party this morning is alarming. There is no instance where violence is acceptable in any political conversation. We condemn this threat of violence and are extremely grateful to local law enforcement for their quick response to this potential threat.

Law enforcement officials say the investigation is ongoing.
