Officials responded to a call about the fire in South Dallas around 6 a.m. Friday and were able to put out the blaze within an hour. Although no one was injured, Jason Evans, Dallas Fire-Rescue spokesman, told NBC DFW investigators found that the fire was arson-related. 

"The fire was determined to be incendiary in nature, and was set at some point at the rear of the building," he told the news station.
