NEW ORLEANS (AP) - Police are searching for three men who fled the scene of a shooting on Bourbon Street in New Orleans last night. 

The gunfire wounded four people in a costumed crowd celebrating the countdown to Mardi Gras. Police have released a video showing people in the crowd staggering into one another and a wall after four shots rang out followed by screams. Police say the video was shot by a bystander and shows an argument involving some people in the crowd. 

New Orleans Police say two men and two women were wounded. The most seriously injured man is in guarded condition with shots to the abdomen, thigh and pelvis. 

Police have made no arrests yet.
