Police continued searching for two men who exchanged gunfire on Bourbon Street in the French Quarter, leaving nine people shot in the crossfire, including two who were in critical condition.

Images captured from a surveillance camera above a bar showed people running down the street in the chaos of the shooting at 2:45 a.m. Sunday.

Police placed several views for the shootout online asking for the public’s help in identifying the two shooters.

New Orleans Police Chief Ronal Serpas said six victims were hospitalized in stable condition. The other victim’s condition was not available. Some of them were tourists.

Serpas said at a news conference in the French Quarter that the victims were shot “by two cowardly young men trying to hurt each other.” “What happened was two young men got angry at each other and shot at each other,” he said.

Bourbon Street is a nightly swirl of bright neon and tourists, usually with beverages in hand.

A blend of jazz joints, strip clubs, bars and restaurants, Bourbon Street has everything from four-star dining to sex shows.

New Orleans Mayor Mitch Landrieu pledged a swift response from law enforcement. “Our No. 1 priority is to keep New Orleans safe,” Landrieu said in a statement. “These kinds of incidents will not go unanswered … I am confident that between video evidence and eyewitness accounts, we will bring the perpetrators to justice.”
