Ten people suffered minor injuries during a car and bike show inside the Georgia World Congress Center Saturday.
GWCC officials said that the incident happened when a fight triggered crowds to rush out of the venue at approximately 8 p.m.
The GWCC said they don't know what started the fight, but are investigating.
Initial reports from witnesses were that they heard gunshots, but police said there was no evidence of shots fired or victims with gunshot wounds. Police believe it may have been a noise maker or toy gun making a popping sound.
The event was radio station V103’s Car and Bike Show. A GWCC official said nearly 30,000 people attended the event that day. Many had left, but there were still thousands of people at the venue when the incident happened.
Police said people were trying to leave the event in a hurry because of an altercation inside. They said a fight broke out and people left, and that was when they were injured.
“Just a massive wave of people running, trampling over people. Baby carriages, shoes, people running out of their shoes, it was a fiasco. It was crazy," said one witness.
One woman was seen being put into an ambulance holding her stomach.
Police say they are still searching for the people involved in the fight that triggered the stampede.
