In one of the more tantalizing leads in the Princess Diana investigation, a new police report quotes witnesses seeing a Fiat Uno "zigzagging" out of the tunnel where she died and describing the car's driver, a judicial source said today.
The source, who spoke on condition of anonymity, is privy to all documents in the case, including the 400-page report police submitted this week to investigating judge Herve Stephan.
The confidential report, coming a full four months after the crash, appears not to contain any earth-shattering revelations. Yet the witness accounts revealed today -- but known to police since Sept. 18 -- are the most detailed so far concerning the mysterious second car long believed to have played a role in the crash.
Investigators have been trying to find a small white car, probably a Fiat Uno, that Diana's Mercedes is believed to have sideswiped just before losing control and crashing into a pillar in the Pont de l'Alma traffic tunnel.
The Aug. 31 accident killed Diana, her boyfriend, Dodi Fayed, and Henri Paul, their driver. Key factors in the crash are still believed to be alcohol -- Paul was legally drunk -- and excessive speed.
The witnesses, who were driving near the tunnel, said the Fiat's driver was "a European type," about 40 years old, with brown hair. In the back of his car was a large dog.
