A report of shots  fired at the Art Institute of Atlanta on Friday morning turned out to likely be an elevator door slamming shut, police said.

Sandy Springs spokeswoman Forrest Bohannon said police responded to the campus at 6600 Peachtree-Dunwoody Road shortly after 10:30 a.m., when they received a 911 call.

Police evacuated the building as a precaution but found no active shooter nor any indication of shots fired.

“It’s possible that during a power outage the fire alarm went off and closed the metal doors in the building, which sounded like gunfire,” Bohannon said.

By 12:30 p.m., the building was cleared and staff were escorted back inside.
