Tuesday September 9 3:04 PM EDT Diana Driver Had Alcohol, Drug Traces in Blood By Christian Curtenelle PARIS (Reuter) - New blood tests on Henri Paul, the driver who died with Princess Diana in a high-speed Paris car crash, showed he had taken anti-depressant drugs before getting behind the wheel, a source close to the inquiry said Tuesday. The tests also confirmed that Paul, whose family disputed initial reports that he was inebriated, had alcohol levels three times over the legal limit for drunken driving, the source said. The source, who asked not to be identified, told Reuters the anti-depressants could have boosted the damaging effect of any drinks Paul took before the crash. Asked whether other substances besides alcohol had been traced in the latest tests, the source said: "Yes, anti-depressant type drugs." He gave no further details. Princess Diana died early on August 31 along with her millionaire companion Dodi Al Fayed and Paul when their luxury Mercedes-Benz crashed into a concrete pillar in a road tunnel while being pursued by paparazzi photographers on motorcycles. A spokesman for the Al Fayed family, which owns the Paris Ritz Hotel where Paul worked, said he had not seen the latest blood test but certainly condemned drunken driving. "If Mr. Paul is culpable, Mr. Mohamed Al Fayed will be the first to condemn him, because he has lost his eldest son and a very dear friend," spokesman Michael Cole told Reuters. The second set of two blood tests was "totally comparable" with previous analyses which found between 1.7 and 1.8 grams of alcohol per liter in Paul's blood. The initial analyses of Paul's blood were performed shortly after the crash by two independent laboratories. "The latest test confirms the earlier tests," the source said. That means he drank the equivalent of two aperitifs and a bottle of wine before he died in the crash along with Diana and her companion Dodi Al Fayed on August 31. French magistrates conducting a criminal inquiry into the causes of the fatal car crash went to the scene of the accident Tuesday to help gather evidence in the case. Paris police accompanied investigating magistrates Herve Stephan and Marie-Christine Devidal during their half-hour tour of the site by the Seine River under the Place de l'Alma in the capital's exclusive Eighth District. Police sources denied reports the car had been filmed by a surveillance camera showing it speeding at 122 mph. The camera was not equipped to record images or measure speed. Investigators believe the car was moving at 90 to 110 mph. The Al Fayed family Tuesday filed civil suits against two weeklies, Paris-Match and France-Dimanche, and two photo agencies for endangering the lives of Diana and Dodi by flying helicopters over their Riviera holiday home last month. Lawyer Alain Dartevelle, acting for the family, said the suits also alleged invasion of privacy. So far in their inquiry, the investigating judges have formally placed under investigation nine photographers and a photo agency motorcycle rider on suspicion of manslaughter, bodily harm and failure to assist accident victims. But more suspects could be added later, including other photographers who may have fled the site before police arrived, or the management of the Ritz Hotel, because of the role the driver played in the crash. Police said they had ruled out mechanical problems with the car as a possible cause of the crash. The vehicle had recently been stolen and several parts were removed by thieves before it was returned to its owner, a limousine rental firm. But the car had been completely repaired and tested for safety by Paris police headquarters before being returned to service, said police officials who spoke on condition of anonymity.
