Three people were injured, including one critically, when a roof collapsed Wednesday afternoon at a home on Flat Shoals Avenue in east Atlanta.

The construction workers were on the roof of the two-story home at the time it collapsed, according to Capt. Jolyon Bundrige with the Atlanta fire department. Investigators have not yet determined what caused the roof to cave in, causing the three to fall about 18 feet.

Three people were pulled out from under the debris and transported to the hospital for treatment, Bundrige said. Two people sustained what appeared to be minor injuries and transported to Atlanta Medical Center. A third person was transported to Grady Memorial Hospital in critical condition.

The home is located in the 600 block of Flat Shoals Avenue.
