Late Thursday night witnesses at Tap Room Bar say they heard a loud noise outside of the bar.
Moments later firefighters and police came out to evacuated everyone from the bar.
Detectives haven't found out what kind of explosive it was but they do believe it could have been a firecracker.
Owners of the bar say if someone was joking around with firecrackers, nothing was funny about chasing away their business on a busy night that Rhythms on the River Concert.
Fortunately no one was hurt.
This investigation is ongoing..
