A man has been arrested at the Cannes Film Festival in France after allegedly firing a gun and brandishing a fake grenade during an outdoor TV interview with Christoph Waltz on Friday (17May13). The suspect's weapon was filled with blanks, but the incident was enough to cause a big scare on the Croisette seafront, where a temporary TV studio had been set up for French show Le Grand Journal for the local Canal + channel. Django Unchained star Waltz was on set during the special festival coverage and was rushed offstage by security at the sound of gunfire. No one was injured and police were quick to tackle the gunman to the ground before arresting the assailant, who has so far only been identified as a 42-year-old male. The broadcast resumed after a short break and presenter Michel Denisot detailed the safety threat to viewers, saying, "He said to a woman next to him, 'If I were you, I wouldn't stick around here...' The police intervened. He had a hand grenade. There were no bullets in the gun and the grenade was a fake." The news comes just hours after it was revealed that a Chopard jewellery collection worth $1 million (£645,000) had been stolen from an employee's hotel room in Cannes. The Swiss gems were intended to be worn by stars attending the prestigious film festival. Leonardo DiCaprio, Nicole Kidman, Steven Spielberg and Emma Watson are just some of the Hollywood celebrities who have already appeared on the red carpet at Cannes, which kicked off on Wednesday (15May13).
