A shooting rampage broke out early Sunday in New Orleans’ famed French Quarter. Ten people were injured, with two in critical condition. 

The shooting occurred on Canal Street, not far from Bourbon Street, at about 3:20 a.m. Victims were taken to the University Medical Center New Orleans and the Tulane Medical Center.

“We do not know how it started,” New Orleans Police Superintendent Shaun D. Ferguson said in a press statement.

No arrests have been made, though one person was taken into custody. Police did not disclose how the person was involved in the shooting.

The French Quarter was particularly busy for the 46th Annual Bayou Classic, a major college football game at Mercedes-Benz Superdome featuring Grambling State University and Southern University. There was heavy police presence in the French Quarter because of the large crowd.

“The shootings on Canal Street early this morning were an ugly disruption of an otherwise beautiful holiday weekend,” New Orleans Mayor LaToya Cantrell posted on Twitter. “This tragedy will not define us, and it will not deter us from moving our City forward and keeping our people safe.”

“To the victims — you are in our thoughts and prayers, and we will work tirelessly to bring those behind this cowardly act to justice,” Ferguson said. “That is a promise.”

Hours after the French Quarter shooting, two people were killed and two more were injured in another neighborhood of New Orleans. Aaron Looney, a spokesperson for the New Orleans Police Department, said there is no connection between the two shootings.
