Mohamed Al Fayed was interviewed by police yesterday in connection with an allegation of sexual assault against a 15-year-old.

The Harrods owner has reportedly been accused of “french kissing” the teenager at the department store in Knightsbridge, West London.

Al Fayed, 75, strenuously denied any wrongdoing and said he was concerned that details of the police interview had been revealed shortly after it ended.

His spokeswoman vehemently denied the allegation of sexual assault.

"We confirm that Mohamed Al Fayed today voluntarily attended an interview with police to categorically refute an allegation widely reported in the media," said the statement. “He did not attend under compulsion and the meeting lasted for less than half an hour."

“From the outset details of this allegation have appeared in the media which they attributed to a police source, and indeed despite assurances that today’s interview would be kept confidential, he is concerned that it was reported within one hour of its conclusion."

“Mr. Al Fayed vehemently denies this allegation and is confident that his name will be cleared.”

After the deaths of his son Dodi and Diana, Princess of Wales, in a car crash in 1997, Al Fayed claimed that they had been murdered in an establishment plot. He abandoned his campaign in April after a jury’s verdict of unlawful killing due to the gross negligence of the driver, Henri Paul, and the paparazzi who were pursuing the couple.
