BATON ROUGE - A club at the center of a shooting that left 12 people hurt over the weekend has agreed to stay closed as officials investigate how someone was able to slip a weapon past security.

Monday morning, more than 24 hours after the shooting, the Dior Bar and Lounge was still very much a crime scene, with investigators from the Alcohol Beverage Commission and Baton Rouge Police stopping by.

Several shoes abandoned in chaos were visible from the street.

Investigators are looking into how someone was able to get a gun into a bustling nightclub and kick off a confrontation that left 12 people shot. 

The Baton Rouge Police Department says it's still looking to make arrests after what Chief Murphy Paul called a "targeted" attack at the Dior Bar & Lounge off College Drive early Sunday morning. 

Police said determining how someone got the weapon inside will be a major focus of their investigation. 

"That is a part of that investigation. We started having contact with our counterparts at ABC, whose regulatory agency involved in this. All of that will be revealed once that investigation has concluded," Deputy Chief Myron Daniels said. "They have also clarified some of the items they will be looking into will be the security breach that occurred from the private security that was working at the event." 

On Tuesday, Councilwoman Jen Racca said owners at the bar handed over their license and  agreed to stay closed while investigators try to figure out how it all happened.

Rashard Rusk is a promoter who says he's worked with Dior several times before. He was standing in line to get in when he heard the gunfire. 

"There are rules for a reason and I feel like rules were broken," Rusk said. "I'm not going to blame the club owner, but that's where all fingers are going to."

"Regardless of the fact, the security that was supposed to ensure that nobody goes in with a weapon, they were hired by you, so all accountability comes back to the owners," he added.

No one has died, but three people were left in critical condition. Sources told WBRZ an artist that was performing that night, DJ Revv, was shot in the spine and is unable to walk. He was not the intended target. 

On Instagram Sunday evening, DIOR posted this message:

"We're deeply sorry for what took place early this morning...We did everything to provide a safe space for our patrons. We took necessary precautions with staffing numerous police officers and security detail"

However, Rusk says those necessary precautions clearly weren't enough.

"They were paid to pat down, they were paid to make sure no weapons were allowed inside the venue and once again a weapon was allowed inside the venue."

We've learned the venue has changed ownership multiple times. In the past, neighboring businesses had complained about capacity violations.

However, according to Baton Rouge Fire Department logs dating back to 2020, there have been no violations.

Baton Rouge Police say they are investigating the security breach with the help of ABC and that the owners are cooperating fully.
