EAST CHICAGO, Ind. — Three people were injured after shots were fired into a crowd at a car show in East Chicago, Indiana, on Sunday afternoon, police said.

According to East Chicago police, the shooting stemmed from an argument between two men who were attending a car show at Jeorse Park Beach.

East Chicago Police Chief Jose Rivera and a deputy chief, who were working the event, sprang into action when several gunshots were fired into a large crowd, causing panic among the eventgoers.

Hundreds of cars were on display on Sunday for the Stunna Beach Bash Custom Car Show and Sound Competition.

“We have a thousand innocent people there. There were people there just enjoying the show. There were kids, there were families,” Chief Rivera said.

According to police, around 3:45 p.m. officers were told that a fight was unfolding near the stage. Chief Rivera and his deputy chief went to break up the fight when they heard gunshots ring out.

“When the first shots went off, we didn’t see who did it, we actually ducked behind the car with everybody else, and when the first round of shots stopped that’s when I got up and saw the suspect continue shooting towards the crowd,” Rivera said.

Chief Rivera chased down the alleged shooter as they attempted to flee between vehicles in the parking lot.

“When he saw me draw my gun, he actually complied. So he tossed the gun, got on the ground,” Rivera said.

According to police, the shooting escalated from an argument about a video game.

“What we’re being told is it’s actually an argument that occurred online over online,” Rivera said. “What they are saying was a video game. These are grown men though, these aren’t kids.”

Rivera said the man who was apprehended was taken into custody and a second individual later turned himself in to the police.

According to police, three eventgoers were wounded in the shooting. Police said one person was taken to the hospital with non-life-threatening injuries and two others later took themselves to the hospital with non-life-threatening injuries.

Officers said all of the weapons used in the shooting were recovered by police.

Police have not yet identified anyone involved and the East Chicago Police Criminal Investigation Division is conducting an investigation.
