The authorities in New Orleans are investigating a shooting that left at least 11 people wounded early on Sunday, the police said.
The shooting, which happened on Canal Street, left two of the victims in critical condition, the police said. It was not clear what had motivated the shooting.
Officers near the scene of the shooting reported hearing gunfire around 3:21 a.m., the police said. They found multiple individuals had been struck by gunfire. No officers were injured.
The police said on Twitter that a person was detained near the scene but that the individual’s “possible involvement” in the shooting remained under investigation, and that no arrests had been made.
The police initially said 10 people had been hurt, but later said on Twitter that an additional victim had walked into a hospital for treatment.
Louisiana State Police and federal officials are helping the New Orleans police in the investigation.
The shooting occurred after the Bayou Classic, an annual football game between two historically black universities, at the Mercedes-Benz Superdome in New Orleans, which draws a large number of visitors.
