VIDEO: More than a hundred residents at a Buckhead apartment complex were displaced after a massive multiple-alarm fire broke out early Wednesday afternoon and quickly engulfed the building.
As Chopper46 flew over the Avana on Main Apartments in the 500 block of Main St. N.E., heavy plumes of smoke could be seen billowing from the building as flames raged out of control. Multiple sections of the building's upper level collapsed during the blaze that started as a 2-alarm fire, but was later upgraded to a 3-alarm fire.
Investigators are still working to determine what caused the fire, but some residents who evacuated told CBS46's Adam Murphy that at least one air-conditioning unit exploded on the roof of the building. They believe that A/C unit then caught on fire, and caused a chain reaction, setting more HVAC units on fire. Other residents told Murphy they heard a loud bang followed by the sound of multiple explosions.
