About 28 people have been confirmed injured after gunfire was heard at the Power Ultra Lounge nightclub in Little Rock.

Rapper Finesse 2Tymes was performing and had taken a break when gunfire was heard.

Police say 28 people were injured in the incident early Saturday; 25 suffering from gunshot wounds. All the wounded are expected to survive.

“Some sort of dispute broke out between people inside,” Little Rock Police Chief Kenton Buckner told reporters, according to the Associated Press.

Police were searching for multiple people believed to be involved in the shooting.

A witness Darryl Rankin posted a Facebook live video of how the shooting started.

After a few sets, Finese 2Tymes stopped for a break. “Whatcha all doing today?” someone asks in Rankin’s video — a few seconds before more than two dozen shots ring out in rapid succession.

Rankin told the Associated Press that one of his friends was hospitalized with a bullet “stuck in his spine.”

The police chief said an off-duty police officer was believed to have been working as a security guard, according to the paper, though police didn’t know if the guard was inside during the shooting.

“I would call it a multiple shooting,” Buckner said. “Some people call it a mass shooting. Too many people shot. One is too many.”
