British police are examining new information about the death of Diana, princess of Wales, reportedly including an allegation that she was murdered by a member of the British military.
Scotland Yard says detectives are checking the "relevance and credibility" of information received recently about the deaths of the princess and her boyfriend Dodi Fayed in Paris on August 31, 1997.
They were killed in a car crash in an underpass, along with their driver, Henri Paul, when the Mercedes he was driving crashed as it was being pursued by photographers.
Citing a military source, the Sunday Telegraph said the allegation came from the estranged parents-in-law of a member of Britain's special forces, who gave evidence in the trial this year of Danny Nightingale, an SAS soldier convicted of illegally possessing a weapon.
The man said to be the source of the allegations, known only as "Soldier N" in the trial, was himself convicted of illegal weapons possession.
The newspaper reported that his estranged wife's parents wrote to the SAS's commanding officer claiming the soldier had told his wife that the unit had "arranged" Diana's death and that this had been "covered up".
The information was passed to the police by the Royal Military Police, according to several reports.
Scotland Yard says it is looking into the matter but that it's not a re-investigation and doesn't come under Operation Paget.
Operation Paget was the initial British investigation into claims of a conspiracy to murder Diana and Dodi Fayed that were made by his father, the former owner of the Harrods department store, Mohamed Al-Fayed.
Led by John Stevens, formerly Britain's top policeman, it concluded in 2006 that all the allegations it assessed were without foundation.
The car that Diana was travelling in smashed into a pillar in the Pont de l'Alma tunnel and spun around.
Dodi Fayed, 42, and driver Paul - the deputy head of security at Al-Fayed's plush Hotel Ritz in Paris - were pronounced dead at the scene of the crash.
Diana, 36, the ex-wife of Prince Charles, the heir to the British throne, and the mother of Princes William and Harry, died later in hospital.
Trevor Rees-Jones, a member of the Al-Fayed family's protection team, survived. He had been the only person in the car wearing a seatbelt.
Seeking to outrun chasing paparazzi photographers, Paul was found to have been speeding, while his blood alcohol level was found to have been more than three times over the French limit.
The longest-running and most expensive inquest in British history concluded in 2008 with a jury finding Diana and Fayed had been "unlawfully killed" by the grossly negligent driving of Paul and following vehicles.
