Witnesses said the shooter ran to a dark-colored SUV on Northside Drive. Sometime later, another round of shots were fired from a white sedan on Whitehall Street, Moorman said.
No one in the crowd was hit in the second spray of bullets.
The Thursday morning gunfire was not the first trouble for the southwest Atlanta nightclub. Police investigated another shooting there earlier this year, and Moorman said there have been issues with crowds and parking in the past.
“We have had to respond to several calls at this location,” he said. “This location does draw large crowds of people here, so we’ve had to address issues.”
In May, an off-duty Fulton County sheriff’s deputy shot and killed a 46-year-old man after an altercation inside the Ivory. Deputies working security fired a stun gun at Norris Duffy before he was seen grabbing an assault rifle from his vehicle, and a deputy fired shots.

Police also investigated deadly shootings at the club in 2015 and 2016.
Moorman said police have met some resistance from witnesses and with club management during their initial investigation. A large crowd in the parking lot scattered when officers arrived, and investigators are hoping more willing witnesses will come forward.
“Any of those people who left before they had a chance to speak to investigators, we are asking them to reach out to investigators or to Crime Stoppers to provide us with any information that can help us to determine what happened here tonight,” he said.
