Prince Charles was questioned by Scotland Yard for several hours last week about the death of his first wife, Princess Diana.
The princess, divorced from Prince Charles, and her boyfriend, Dodi Fayed, the son of the owner of the upscale department store Harrods, died on Aug. 31, 1997. Their chauffeur-driven Mercedes went out of control as it was pursued by photographers in a Paris road tunnel. The driver, Henri Paul, was killed, and the couple's bodyguard, Trevor Rees-Jones, was critically injured.
Prince Charles was formally interviewed by Scotland Yard as part of its original investigation. They reportedly questioned him for several hours about events leading up to deaths.
The French inquiry into the princess's death found that it was an accident. The French blamed Diana's driver, who they said was driving under the influence of alcohol.
So far, the $5 million British investigation has already been one of the costliest in the nation's history.
Before her death, Diana apparently wrote a letter saying she believed Prince Charles and his friends were plotting her death.
"My husband is planning 'an accident' in my car, brake failure and serious head injury," she wrote, speculating it was "to make the path clear for him to marry."
Her butler shared the letter with the public a few years ago.
"We are frankly mystified," ABC News quoted British royal biographer, Robert Lacey as saying. "This document was talked of as a letter. If it is a letter, we don't know at the moment who the princess was writing to — with whom she shared this extraordinary allegation."
