LATEST: The photographers who took the controversial images of British royal DIANA, Princess Of Wales in her final moments are suing U.K. TV network Channel 4 for "stealing" the pictures for use in their programme. The Channel 4 show The Witnesses in the Tunnel was broadcast on national television last Wednesday (06Jun07) - despite pleas by Diana's sons, Princes William and Harry, to axe the documentary altogether. Among the pictures contested is one of Diana slumped in the back seat of the Mercedes moments after the fatal 1997 collision in Paris, and another showing a French doctor attempting to fit an oxygen mask to her face. And photographers Fabrice Chassery and David Kerr have now launched legal proceedings against the network for failing to acknowledge their letter - a carbon copy of which has been forwarded to the princes' representatives - which pleaded for the photos not to be used. They claim that the images were taken as evidence by the French Police and are meant to remain in Paris under "lock and key". Chassery says, "These pictures were taken away by the Paris police ten years ago and are supposed to still be under lock and key. "I told (the show's producer) Janice they must have been stolen. We had a number of meetings and were offered thousands of euros. Janice kept saying, 'We have a big budget.' But I told her, 'Do not use the picture. You have to think about how this will upset William and Harry. It is wrong.' She just said they had got another picture from someone else. "I am the only photographer who has ever laid claim to having taken this picture. I have never sought to profit from it but I want damages from Channel 4 for stealing it and I want it never to be shown again."
