International news media reports say two of the victims were rushed to hospital in critical condition.
Multiple reports say the suspect has been detained.
One report said: “New Orleans Police had already increased their presence in the area because of the Bayou Classic football game between Grambling State University and Southern University.
“Officers confirmed they were just a few feet away from the shooting, and initially thought they were being fired at.”
NOPD Supt Shaun Ferguson confirmed that “a person of interest has been detained. He emphasized that it’s unclear what involvement, if any, the person of interest had in the shooting”.
