Residents reported hearing some sort of explosion and then saw flames coming out of the Heather Croft complex late Wednesday night.

Assistant Fire Chief William Hancock tells WMGM-TV  three units were destroyed and 12 sustained smoke or water damage. But fire walls helped contained the blaze from the other units in the building.

There's no word on a cause.
