The Knoxville Fire Department is investigating a house fire in Northwest Knoxville.

Crews called to the 3200 block of Dewine Road this morning. The home has suffered heavy fire damage to the attic space and moderate smoke and water damage.

The home had working smoke detectors. However, the detectors did not alert the occupants because there was little to no smoke inside the home at the time of the fire.

No injuries reported.
