Investigators shared a photo of the suspect on social media.
They say just after midnight, during a dance party hosted for college students in the bar, a fight broke out and a man started firing his gun toward the ceiling multiple times.
The gunfire sent the crowd running but investigators say no one was injured by gunfire or when they tried to get away.
They say the gunman was wearing a light grey sweatshirt, light denim jeans and was last seen running north on MacReady Drive.
