Police still had no suspects in custody Sunday after a weekend shooting near an Ohio street festival wounded 12 people and sent attendees scrambling for cover in a busy Toledo neighborhood.

Police Chief Joe Heffernan said it appeared that at least two people fired weapons on Saturday near the Old West End Festival and were probably shooting at each other.

Authorities say a search for the shooters was ongoing and had not identified any potential suspects. They urged festivalgoers to come forward with any photos or videos.

Toledo police Lt. Dan Gerken said. Twelve people being shot, that’s the most I’ve been to a scene. I’ve been to a lot of scenes, but this is way over the top.

Hundreds of people were at the festival, an annual two-day celebration in Toledo’s historic district that includes live music, food vendors, home tours and shopping.

The remainder of the festival was canceled Sunday. Organizers said it would not be compassionate, responsible or possible to continue.
