Actress Jodie Turner-Smith’s hotel room has been targeted in the latest high-profile heist to hit Cannes.

Jewellery reportedly worth tens of thousands of pounds was seized when the actress’ suite in the luxury five-star Marriott hotel on the beachfront was plundered in a daytime burglary.

French police in the Riviera are investigating the fifth major theft in eight years after the star of Channel 5’s Anne Boleyn reported the burglary on Friday, July 9, less than 24 hours after she debuted on the red carpet.

Ms Turner-Smith, attending her first Cannes Film Festival with her one-year-old daughter, is understood to have been out when the burglary took place.

Local sources have stated that the hotel room door, opened with a magnetic key card, showed no sign of forced entry and there were no injuries.

The Marriott has stated that it will help with the investigation overseen by the Judicial Police based in Nice, adding that “the security of our guests is our top priority”.

Ms Turner-Smith announced on Sunday that: "I didn’t think I would be spending 2.5 hours in the police station on my final day in Cannes, but here we are."

Police have made no arrests so far, and authorities on the Cote d’Azur will not confirm the exact nature of the items taken in the burglary while the investigation is underway.

The actress had sported a diamond-encrusted gold Gucci necklace on the red carpet but it is understood the pieces were returned prior to the burglary, which took place between 10am and midday.

While the Gucci items may have been saved, film industry trade magazine Variety, which hosted an event with the actress on Sunday in the wake of the crime, has reported that her mother’s wedding ring was taken in the theft.

Cannes: “A sunny place for shady people”

Ms Turner-Smith has now been given bodyguards and moved to another hotel on Cannes’ lavish La Croisette boulevard.

The seafront street boasting designer fashion stores and luxury hotels has been the site of numerous jewellery heists since Cannes began attracting film stars through its annual festival, and in the past 10 years hundreds of millions of pounds’ worth of jewellery has been stolen.

Thefts, including the snatching of £100 million worth of jewellery from the Carlton in 2013, have been so sophisticated that they have been attributed to the international network of jewellery thieves known as the Pink Panthers.

The National Police in Cannes have given no indication of who they believe was behind the latest crime, but have maintained a large presence in the town during the film festival.

White-uniformed officers have been conducting frequent, 20-30 strong patrols through the resort town, and a security detail has been spotted outside the Marriott on the beachfront.

Access to the Marriott has not been restricted, with guests coming and going alongside press and delegates working in the building.

The Palais where the film festival is headquartered is ringed by security guards and French riot police, the CRS. The festival has now indicated it will increase the level of security at the complex.

Ms Turner-Smith, who has reportedly been moved to the nearby Majestic, has continued to keep her engagements despite the burglary, and headlined an event for women in cinema on Sunday.

The Kering Women in Motion event was followed by a black-tie dinner hosting the Cannes elite, which was interrupted to broadcast the European Championship.

The concession to air the match between England and Italy was made after Cannes jury president and film director Spike Lee was spotted gazing at the game on a TV screen at the event.
