The usually peaceful community in the Southport section of Fairfield was shaken early Sunday morning after reports of a shooting inside Wafu Asian Bistro.

News 12 reported that police responded to the bistro to reports of shots fired. They found shell casings inside and outside the location but no victim.

Police were later informed that a man who said he was shot in Southport was being treated at Bridgeport Hospital. He had a gunshot wound to the arm and injuries not considered life-threatening.

Police say he is not being cooperative with the investigation. They told News 12’s Lauren Fabrizi that the incident stemmed from an argument between two groups, which then became violent.

Police believe the owners work with promoters to turn the restaurant into a nightclub after hours. Lt. Michael Paris, of the Fairfield Police Department, says it has been “on their radar” for several months. State agencies are assisting in a probe of the establishment.

Police are pulling surveillance video and asking anyone who may have cellphone video of the shooting to come forward. A suspect is said to have fled the scene in a car.

News 12 has reached out to the bistro but has not yet heard back.
