Chief Buckner said it was “concerning” that an advertisement for the concert included a photograph of the headlining performer, the rap artist Finese 2Tymes, pointing a gun toward the camera.

He said that the Memphis-based performer’s real name is Ricky Hampton, and that Mr. Hampton had two warrants related to violence in other cities.

The club shooting is the latest in a string of violent crimes in Little Rock, where local news outlets have reported several drive-by shootings in recent days. “This is, I guess, a blip on the map that we certainly didn’t need considering the history that we’ve had over the past week,” Chief Buckner said.

He said some warrants had been issued for suspects in the recent drive-bys. “So at a time when you feel like you had some momentum to get some of the individuals responsible for those shootings, we had this incident happen,” the chief said.

He said it was too early to tell whether the separate shootings were related.

State officials revoked Power Ultra Lounge’s liquor license on Saturday morning. “We found this emergency action was required to preserve the public safety, health and welfare,” said Boyce Hamlet, the director of Alcoholic Beverage Control Enforcement in Arkansas.

Bruce Moore, Little Rock’s city manager, said the Power Ultra Lounge had been zoned as a restaurant, not a club and event space. He added that he was asking the city to shut down the venue.

Gov. Asa Hutchinson called for a law enforcement strategy to address crime rates in the city and promised help from the state.

“Little Rock’s crime problem appears to be intensifying,” Mr. Hutchinson said in a statement on Saturday. “Every few days it seems like a high-profile shooting dominates the news, culminating in this morning’s event.”
