Police say a physical altercation broke out at the Twelve Mile Lounge around 1 a.m. on Mar. 18.

Investigators believe it happened in the lower level of the bar, close to the stage. They say security stepped in to break up the fight and escorted everyone involved out of the bar.

One person was taken to hospital for medical treatment and was later released.

Police are looking for a white male, roughly six-foot-one, in his mid to late twenties, 255 lbs, with a short, buzzed haircut, and scruffy beard. The man was wearing a black shirt and blue jeans.
