A man was shot along the Uptown New Orleans parade route Saturday in what investigators believe was an accident.

According to police, the shooting happened around 2:30 p.m. near St. Charles and Napoleon avenues.

Mayor Mitch Landrieu and Police Superintendent Michael Harrison addressed the media at the scene and said the victim was shot in his side after someone handling a gun inside a portalet fired a shot through the wall. The NOPD said investigators think the shooter might have "mishandled the weapon."

The victim, from Metairie, was wounded while he was standing on the neutral ground.

There was no altercation preceding the shooting, and investigators were canvassing the area for evidence that could help identify the shooter, police said.

"Turned around and saw a man on the ground bleeding from his side," said eyewitness Lalo Salas, who's visiting from Dallas. "I didn't see anyone with a gun. We heard the gunshot."
