Officials and rescuers on Tuesday stated that false rumors of a shooting spread on the main promenade of the town of Cannes.
By 4am (0200 GMT), emergency services counted 44 injured individuals who were brought to the hospital by ambulance or made their own way there.
A rescuer shared that the majority of the injuries were minor, mainly to the lower leg.
Rumors of a shooting sent holiday-makers and diners running into one another and scrambling to escape a threat that never existed.
Almost 100 emergency service personnel were deployed to the Croisette promenade to deal with the aftermath of the mass panic that hit the glitzy resort town best known for hosting the Cannes Film Festival.
Amateur videos of the crush posted online show people ducking under dining tables and running fearfully in all directions on the seafront promenade, lined with luxury boutiques, which annually rolls out the red carpet for the world's movie stars.
"There were no gunshots in Cannes," mayor David Lisnard tweeted around midnight, but rather an outbreak of "collective panic after an individual shouted 'gunshot'".
