A shooting near a popular street festival in Toledo, Ohio, left at least a dozen people injured Saturday, turning a community celebration into a chaotic scene as attendees sought safety and others assisted the wounded.

Authorities said no arrests had been made as of Saturday evening. Toledo Deputy Police Chief Joe Heffernan urged anyone who attended the event and may have captured photos or video to share that material with investigators as they work to identify those responsible.

The gunfire broke out in the vicinity of the Old West End Festival, an annual event known for its live entertainment, historic home tours, and large crowds.

According to Heffernan, preliminary information suggests that at least two individuals exchanged gunfire. Investigators believe the shooters may have been targeting one another.

Twelve people were wounded in the incident, including two who remained in critical condition. The victims ranged in age from 14 to 61, though most were in their early twenties.
