LITTLE ROCK, Ark - At least 17 people were shot in Little Rock, Ark., after a dispute broke out at a nightclub concert, police said early Saturday.

One person has been upgraded to stable condition from critical police tweeted Saturday. The youngest person shot is 16-years-old, Little Rock police chief Kenton Buckner said in a statement. Police tweeted that all 17 victims were alive Saturday.

The shooting, which took place at Power Ultra Lounge around 2:30 a.m. local time, does not appear to be terror-related or an active shooter incident, Buckner added.

Other people were injured exiting the club during the chaos, though it was not clear how many were hurt, Buckner said. Glass and empty drink cups littered the ground outside the two-story building as police cornered off the block, the Associated Press reported.

Buckner added it was too early to provide details about the suspect but that it was possible there could be multiple suspects. "Certainly during incidents such as this, emotions are very high. We need to be very careful with our words," Buckner said. "This is a blip on the map that we certainly didn't need, considering the history that we've had over the past week." Little Rock Mayor Mark Stodola thanked first responders and area hospitals in a Facebook post Saturday. "My heart is broken this morning — my prayers are with the victims of this tragedy," he wrote. "We are committed to doing everything possible to bring safety to our city. We need everyone to help." The shooting occurred during a concert featuring Finese 2Tymes, a Memphis rapper. A Facebook post promoting the event from Power Ultra Lounge shows a photo of a man pointing a gun at the camera.
