Two gunmen remained on the loose in New Orleans on Sunday after firing "indiscriminately" into a crowd outside a daiquiri shop and killing three people on Saturday, police said. Seven other people were injured.

Police said Sunday night that they believed the incident was gang-related.

"Two individuals clothed with what we believed to be hoods ... approached from behind, right in front of the daiquiri shop right behind us, and opened fire, one with, we believe, a rifle and one with a handgun on the crowd, " New Orleans police Supt. Michael Harrison told reporters late Saturday.

"We believe they actually stood over one of the individuals and fired multiple rounds and then after that fled," he said.

"This has to be personal," he added. "Firing indiscriminately into a crowd? Shooting 10 people? Killing three? That's personal, it doesn't get more personal and we take it personal, whoever did this, you should know that the law enforcement takes it personal and we’re coming for you."

Two men and a woman were pronounced dead at the scene. Police said none of the survivors' injuries was believed to be life-threatening.

The shooting happened Saturday night on Claiborne Avenue, about three miles from the French Quarter, New Orleans police spokesman Aaron Looney said a statement.

Mayor LaToya Cantrell condemned the violence in a statement released soon after the shootings.

There is no place in New Orleans for this kind of violence. I speak for everyone in our City when I say we are disgusted, we are infuriated, & we have had more than enough. Three more lives — gone. It has to end. It’s unacceptable anywhere. pic.twitter.com/WqUWcf75V3 — Mayor LaToya Cantrell (@mayorcantrell) July 29, 2018
