Videos shared on social media that have since been removed showed gunfire, shouting and chaos as shots erupted inside and outside the Stadium Ultralounge & Bar, a night club across the street from Bon Marche on Florida Boulevard, early Saturday.

Baton Rouge Police Department spokesman Sgt. Don Coppola Jr. said investigators believe some type of escalating altercation took place at the club. Shots were fired both inside and outside the club. Seven people were injured. It's unclear how many were hurt by gunfire.

One video appeared to show a man hitting another person with a glass bottle. Then someone in a blue shirt starts shooting in the direction of the person who was swinging with the bottle.

Another video shows a closer look at the man swinging the bottle. Once shots are heard, bar patrons are heard yelling, "Go, go, go!"

At least four gunshots can be heard in the video.

A third video appears to show another round of gunfire outside the nightclub.

EMS spokesman Nick McDonner said they transported five patients to the hospital. Two had potentially life-threatening injuries, he said. He said others injured may have been driven to the hospital by those at the club.

Police are urging anyone with information about the incident to come forward.
