Details of the fire late Monday morning were not immediately available, but video from WSB-TV showed about two-dozen firefighters on the roof of a building at the complex. There were no reports of any injuries.
On May 1, more than 100 firefighters battled a blaze that ripped through a simulated streetscape at the studios, sending flames about six stories into the sky.
Atlanta Fire Chief Kelvin J. Cochran has said the cause of the May fire would be recorded as undetermined. Cochran said the intensity of the May fire consumed any evidence that would lead to a cause of ignition.
