The UK’s Metropolitan Police on Friday referred itself to the police watchdog following complaints from two women over its handling of investigations into alleged sexual abuse by late Harrods owner Mohamed Al-Fayed.

The complaints, referred to the Independent Office for Police Conduct (IOPC), involve investigations from 2008 and 2013.

They revolve around the quality of the police response and, in the case of the 2013 probe, how details came to be disclosed publicly.

“In recent weeks, two victims-survivors have come forward with concerns about how their allegations were handled when first reported, and it is only appropriate that the IOPC assess these complaints,” said Stephen Clayman, from the Met’s Specialist Crime team.

“Although we cannot change the past, we are resolute in our goal to offer every individual who contacts us the highest standard of service and support,” he added.

More than 400 women and witnesses have come forward in the past six weeks alleging sexual misconduct by Fayed, who died in August last year aged 94.

The allegations follow the airing of a BBC documentary in September that detailed multiple claims of rape and sexual assault by the former owner of the upmarket London department store.

The Justice for Harrods Survivors group said it had received 421 inquiries, mainly related to the store but also regarding Fulham football club, the Ritz Hotel in Paris and other Fayed entities.

The Met said Friday that it was “actively reviewing 21 allegations reported to the Metropolitan Police prior to Mohamed Al-Fayed’s passing… to determine if any additional investigative steps are available or there are things we could have done better.”
