PEORIA, Ill. -- A scary situation for some people watching fireworks last night at Glen Oak Park.
Toward the end of last night's show, authorities say a stray firework shell exploded near a group of spectators next to the amphitheatre stage.
Authorities say 12 people were treated at the scene and two people were treated for burns.
There were no reports of any serious injuries.
It was an unfortunate ending to an otherwise pleasant evening at the park.
The City of Peoria Fire Department says they have further investigated last night's incident.
They're hoping to prevent a similar accident from happening at the riverfront tonight.
"We don't expect there to be problems however we do have an instant action plan in place with law enforcement, with fire, with the medical community to take care of anything that would occur," said Fire Arson Investigator Brad Pierson.
But last night's incident didn't stop people from claiming their perfect spots early for tonight's firework show.
Hundreds of people flocked along the Riverfront to get the perfect view for the Unity Point Health Methodist Proctor Red, White and Boom festivities.
Grills, tents and lawn chairs were among several items set up for the ultimate 4th of July celebration.
Carla Mobley brings her granddaughter for the fireworks every year and says she's happy the one's tonight will be coming from the barge on the river.
"We've got plenty of room to back away because it's kind of out in the water. You know, every now and then somebody does get hurt. It's a hazardous thing. But, we've got plenty of room," said Mobley.
Over 100,000 people are expected be out at the riverfront this evening.
The fireworks show is scheduled to start at 9:30 p.m.
