Police hunt for new Diana clues

Police photographers and surveyors used laser equipment to scan the Paris tunnel where Diana, Dodi Al Fayed and their driver died in a crash in 1997.

The move followed a request by the coroner who will carry out the inquest.

A computer model of the scene will be created, which police said would "enhance understanding" of the crash.

Met Police officers were on hand to use the laser equipment, Scotland Yard confirmed.

The three-dimensional model will use new technology that was not available at the time of the accident.

Diana, her partner - Mr Al Fayed - and their chauffeur died after their Mercedes crashed in the Pont d'Alma Tunnel after leaving the Ritz Hotel on the morning of 31 August, 1997.

The subsequent investigation concluded that driver Henri Paul had been drinking and was driving at high speed.
