Authorities said that four people were injured after an explosion at an apartment complex in an Atlanta suburb Sunday afternoon. The Dunwoody, Georgia police department received a call at 1:24 p.m. about the explosion at the Arrive Apartments, a luxury apartment approximately 15 miles north of downtown Atlanta. At least 15 to 20 units of the three-story building were damaged in the blast, Dunwoody Deputy Fire Chief Melvin Carter told reporters at a news conference Sunday afternoon. Jaeson Daniels with DeKalb County Fire Rescue confirmed that four people were transported to the hospital with minor injuries.

The DeKalb County Fire Rescue Department completed its search and evacuation of the building and confirmed no one is trapped, the department said in a statement on Facebook on Sunday night. The structure was stabilized after rescue teams shored up the parts of the building that were structurally unsound so they could be searched, the fire department said.

According to the Dunwoody Fire Department, a leasing manager called Atlanta Gas prior to the explosion about a reported gas order, but the cause of the explosion is still under investigation.
