Six people are facing charges, stemming from an overnight bar fight in downtown Knoxville.
A gun was also fired during the incident, just before 3:00am Wednesday morning, at the Red Iguana on South Central Street in the Old City, but authorities say no one was injured.
Investigators say the gun, carried by 25-year-old Robert Wilder, unintentionally fired inside the bar, causing customers to scramble into the street, where several fights erupted.
A security officer at the club was struck with a pool cue and treated for his injuries.
Wilder is facing five charges, including reckless endangerment and weapons charges.
Four men and one woman, arrested in connection with the fights, are now facing disorderly conduct charges.
