French police are raiding the offices of the magazine that published pictures of the Duchess of Cambridge topless.
The raid comes a day after the Duke and Duchess won an injunction to stop Closer magazine publishing more pictures of Kate as she sunbathed at a private villa.
The injunction was granted after William and Kate took legal action complaining that their privacy had been invaded and that the photos could only have been taken from a powerful telephoto lens.
"These snapshots which showed the intimacy of a couple, partially naked on the terrace of a private home, surrounded by a park several hundred metres from a public road, and being able to legitimately assume that they are protected from passers-by, are by nature particularly intrusive," the French civil court, the Tribunal de Grande Instance, decreed in Paris.
The magazine - part of Montedori, a group owned by former Italian PM Silvio Berlusconi - was ordered to hand over all its files of the pictures to the royal couple within 24 hours or face a €10,000 (£8,070) daily fine.
However, the magazine has not disclosed the name of the photographer who took the pictures so the court has not been able to insist that he or she hand over unpublished pictures, or give the copyright to the Duke and Duchess.
