NASHVILLE, Tenn. (WKRN) – An investigation is underway after an overnight fire at a church in Germantown was believed to be intentionally set.

The Nashville Fire Department responded to The Axis Church off 2nd Ave North just before 2:00 a.m. Tuesday. Crews found a small fire burning inside the location and used a watering can to extinguish it before clearing out the smoke in the building.

“Axis family, overnight there was a molotov cocktail thrown through a window and causing a fire at our building,” church leaders posted to Facebook.

According to the NFD, firefighters are required to notify ATF anytime there is a fire at a church. The NFD believes the fire was intentionally set and there is an active investigation underway.

Church officials are asking neighbors if they could share any video footage from the street or to reach out if they witnessed anything suspicious between approximately 9:30 p.m. Monday and midnight Tuesday.

Fire investigators initially told News 2 the fire may have been started by a coffee maker that was left on overnight.
