The Evansville Police bomb squad was called to an area on the city's west side to investigate a possible explosion.
It happened around the area of Tekoppel and Lloyd just before 10:00 Tuesday night.
Evansville Police tell us they believe someone altered a firework to make it into an explosive device and threw it under the Lloyd overpass at Tekoppel.
The bomb squad says people in the area reported a loud boom. They say the area was checked for secondary devices and nothing was found.
Members of the bomb squad say it's important for people to understand that once you alter a legal firework, it becomes illegal and could lead to felony charges.
"Anytime you contain a firework, depending on what you contain it in, that makes fragmentation, shrapnel and it flies out like a regular IED," Sgt. Steven Evans said. "It's kind of like a grenade. It's explodes inside and the shell cracks and it comes flying away."
No one was injured as a result of the incident.
Police say they are investigating and they have a vehicle description. Anyone with information on the incident should call 911.
