Fifteen people were shot and one person was killed at a Cincinnati nightclub early Sunday morning, officials said.
Cincinnati police originally said there were "at least a couple of shooters" who opened fire inside of Cameo nightclub, but later said only one shooter was responsible for the deadly assault.
Assistant Police Chief Paul Neudigate says in a tweet there was only one reported shooter but police are still investigating.
The motive for the shooting remains unclear, and Neudigate says there is no indication the attack is terrorism related. The shooting occurred around 1:30 a.m., WLWT reported.
“We are in the middle of a very horrific situation that occurred at the nightclub with multiple victims,” Paul Neudigate told WLWT. “It’s going to be a long night for our homicide units to investigate.”
The victims were taken to four area hospitals. Some drove themselves and others were taken by ambulance. WLWT reports that at least one of the wounded is in critical condition at a hospital.
Capt. Kim Williams says authorities are not sure what prompted the shooting.
"Saturday night, it is a very young crowd. We have had incidents here in the past, but this is by far the worst," Capt. Kim Williams said.
Several officers were working security detail at the club and performed first aid and tried to revive the person that died, Williams said.
Williams added that the scene was chaotic when the gunfire erupted, prompting a lot of people leaving the scene.
"The biggest problem when you have a large crowd like this and the shots ring out, a lot of the witnesses disappear," Williams said.
Police are interviewing witnesses and asking anyone with information to come forward.
Police do not have any suspects at the moment, and the investigation is ongoing.
