Officers were called to Shell Gas Station on Warm Springs Road just after 10 p.m. for a report of shots fired.
"Upon arrival, responding officers found several gunshot victims and a large group of people," the Columbus Police Department said in a Facebook post on Saturday, NBC News reported.
Police Chief Freddie Blackmon said at a news conference that they believe there was an altercation at a nearby party and it spilled over to the gas station.
The 5-year-old was at the gas station with a family member, Blackmon told reporters.
The other victims included boys ages 12, 13, 14, 17, and two who are 15. Two girls, both 13, were also injured, according to police. All of the victims have non-life-threatening injuries and are being treated at local hospitals. Four of them were released, the police chief said at the news conference.
As of Saturday afternoon, no arrests had been made. Anyone with information is urged to contact the police.
Blackmon said there has been a "rash of gun violence involving our youth" happening across the country, and the only way to combat it is with "community effort."
"While Columbus is not immune to these incidents, I want to assure citizens that the men and women of CPD are tirelessly working to get violent offenders off our streets," Blackmon said in a statement. "The entire village has a responsibility because incidents like this impacts all of us."
