ARLINGTON, Texas — This story has been thoroughly updated.
Investigators are looking into a reported explosion that happened Saturday morning at an Arlington home that was under construction, officials said.
The Arlington Fire Department said crews responded to reports of an explosion and fire in the Viridian neighborhood in northern Arlington. The home was located on Crystal Oak Lane.
According to the department, the structure that was on fire was unoccupied and suffered "major structural damage."
The fire department said it appeared the apparent explosion happened due to a gas appliance "that was not fully turned off."
Security video from a nearby resident showed the moment the explosion occurred. The blast caused car alarms to go off.
Fire department crews are still assessing the damage to the home and other surrounding homes to determine if the area is safe. Atmos Energy said its technicians were called to the scene to check on the company's system in the area, and the Railroad Commission of Texas said Monday it is also investigating the explosion.
"Atmos Energy has verified that our system is operating as expected, and we have found no indication that our system was involved," the company said in a statement.
The fire department said there shouldn't be any reason for alarm for nearby residents with gas appliances.
