DECHERD, Tenn. (WKRN) – An investigation is underway after multiple buildings caught fire early Tuesday morning in Decherd.

At 2:45 a.m., the Decherd Police Department announced that multiple buildings had caught fire on East Main Street across from the post office.

Crews at the scene shut down the roadway from the railroad tracks to Diagonal Street as they worked to extinguish the blaze. One lane has since reopened, according to Decherd Police Chief Kenneth Griffin.

Motorists were asked to seek alternate routes Tuesday morning to travel to work and school.  

The Decherd Fire Department, along with five other agencies, responded to the scene to fight the flames.

Griffin said three major structures were damaged — a storage building, a private building and one business. He told News 2 that TBI has arrived to investigate what led to the fire.

At the scene, a commander told a News 2 crew that a firefighter was hit in the face with a hose stream, but no serious injuries were reported.

The fire remains under investigation. No other information was immediately released.
