A man who sought $15 million from Mohamed Al Fayed for documents alleging that his son Dodi and Princess Diana were murdered was arrested in Vienna last week in a sting involving the FBI and the CIA, Austrian Interior Ministry spokesman Rudolf Gollia said Wednesday. When authorities arrested him, the man, identified only as a 67-year-old Austrian living in the U.S., yelled threats at Al Fayed, the Kurier daily reported. Gollia said the man had contacted Al Fayed, the owner of London's Harrods department store, and offered to meet him in a hotel in Vienna for the exchange. Al Fayed sent Harrods' security chief, John Mcnamara, to meet the suspect and alerted the FBI, CIA and the Austrian intelligence agency. Austrian authorities are working in conjunction with the FBI and CIA to determine if the documents are authentic, Gollia said. Meanwhile, the CIA has issued a statement saying "any assertion that the CIA played any role" in the death of Princess Diana is absurd.
