NEW ORLEANS (AP) - New Orleans police have made no arrests yet, but they are searching for three men after a shooting on a crowded Bourbon Street last night.

The gunfire wounded four people in a costumed crowd celebrating the countdown to Mardi Gras. Police have released a video shot by a bystander that shows one of the victims involved in an argument just before shots were fired. People in the crowd can be seen staggering into one another and a wall after four shots rang out followed by screams.

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.
