A man died and nine other people were injured in a shooting early Sunday in New Orleans' French Quarter, police said.

The shooting occurred before 1:30 a.m. CT on Bourbon Street, Chief Michael S. Harrison said during a news conference. Several officers were already on patrol in the French Quarter after the Bayou Classic, a football showdown between Grambling State University and Southern University. The officers who heard the shots fired ran to the scene and found two women and eight men shot.

“We do not have the information about what precipitated the shooting right now, other than shots were fired,” Harrison said.

One man was pronounced dead at the hospital, Harrison said. He was not identified. Harrison said the other victims are listed in "varying conditions."

Police arrested two men, a shooting victim and a bystander, on firearm possession charges. Harrison said it was unclear whether the bystander was involved in the shooting.

Harrison, who said eight other firearm arrests were made over the past 24 hours in the French Quarter, expressed disappointment that people brought guns despite law enforcement's pleas to leave the weapons at home.

"We’ve made a strong message that this was not the place or the time to bring firearms to the French Quarters during the Bayou Classic event or any event," Harrison said.

Mayor Mitch Landrieu called the incident unacceptable, especially following a major city event.

"t really is heartbreaking, especially on a night like this," he said. "It was a beautiful game. Everyone was working really well with each other throughout the whole city. It's just a tragic end to what was otherwise a beautiful weekend."
