KNOXVILLE, Tenn. (WATE) — Fire crews responded to the scene of a vacant house fire Thursday morning in the Fountain City area north of Knoxville that they believe had been illegally occupied, according to the Knoxville Fire Department. Investigators are also asking the public for additional information related to the incident.

KFD spokesman Mark Wilbanks said in an email news release that crews responded to the scene after a call reporting the fire came into Knox county E-911 at 6:08 a.m. Arriving crews with the initial engine company saw flames coming from the rear of the house. Firefighters were able to quickly extinguish the flames of a small fire found inside the home.

Wilbanks says the home was moderately damaged by the fire and it was vacant at the time; however, it did appear that people had been illegally occupying the home when the fire occurred.

KFD investigators are working to determine the cause of the fire.

Cedar Lane at Pratt Road was blocked this morning for a short period of time. However, Cedar Lane is now open to traffic. If anyone has any information about the fire, please call the Tennessee Arson Hotline at 1-800-762-3017 or The KFD Hotline at 865-637-1368
