A man was arrested Saturday in a shooting outside a downtown Atlanta lounge that injured three people, including a security guard.

The shooting near the CRU Hookah Lounge on Peters Street was the second investigated by Atlanta police Saturday. The two incidents are not connected, according to police.

Around 10 p.m., officers responded to the lounge regarding reports of multiple people shot. An off-duty Atlanta police officer working nearby heard the gunfire and responded to the area as well. At the scene, three men were found shot and were all stable when they were taken to a hospital.

“The preliminary investigation indicates at least one person began shooting outside of 301 Peters Street,” a police spokesman said in a statement. “A security guard at 301 Peters Street responded to the gunfire and it appears he fired toward one of the suspects and was himself struck by gunfire at some point during the confrontation.”

The off-duty officer was able to provide a description of the suspect and responding officers quickly apprehended him. He was identified as 25-year-old Nile Lewis and was arrested on a charge of aggravated assault. At the time of his arrest, he was armed with two handguns, police said.

The first incident happened around noon in northwest Atlanta, where officers were dispatched to West Lake Avenue and Joseph E. Boone Boulevard. When they arrived on scene, they were advised that the victim was at a nearby fire station, police said. The man was stable when he was taken to a hospital.

The preliminary investigation revealed that the man had been involved in a fight with the suspected gunman prior to the shooting, police said.

“It appears the shooting is related to the dispute,” police said but did not clarify if the suspect and victim knew each other.

Authorities said they are still trying to identify the suspect in the earlier shooting.
