HOLLY HILL, Fla. -- A powerful bomb exploded in a Holly Hill park. Now investigators are on the scene to try to figure out what the bomb was made of and who set it off.

They're saying it's a good thing no one was around when it went off, because this was a big bomb. Investigators are still looking for pieces of the bomb, which are scattered all over the place.

The bomb was in a trashcan there. Investigators say, this was no ordinary pipe bomb.

"This is not a chemical bomb that some kids did. This is a major explosion," an investigator told Channel 9.

The Volusia County Bomb Squad is on the scene making sure there are no more devices. They did have their dog out earlier and he didn't find anything.

Investigators are going to be on the scene for some time, trying to find every little piece of the bomb that they can.

If you have any information, there is a $2,500 reward for a tip that leads to an arrest.
