"Do not convey false information"

"There was neither a gunshot in Cannes, nor a madman entrenched but a collective madness after an individual shouted 'gunshot'. We are making the final doubts," tweeted the mayor of the city David Lisnard. "The crowd movement was caused following a rumor. (...) The situation is under control. We thank you for not conveying false information", denied the city of Cannes on Twitter, while many videos of people in panic were circulating on social networks.

According to a witness on the spot contacted by AFP, terraces were overturned on the Croisette after a crowd movement left from the beach Barrière le Majestic: "People in panic were screaming and some fell to the ground", specified Jacques Benaroch .
