The late Egyptian billionaire Mohamed Al Fayed sexually abused female staff at his London department store Harrods, forced them to have medical screenings and threatened consequences if they tried to complain, lawyers for alleged victims said on Friday.

One woman who had worked for Fayed at the luxury Knightsbridge store called him "a monster".

Harrods apologised on Thursday after more than 20 women told the BBC Al Fayed had sexually abused and in some cases raped them. He died last year aged 94.

"Underneath Harrods glitz and glamour was a toxic, unsafe and abusive environment," lawyer Gloria Allred told a press conference.

She said the allegations included serial rape, attempted rape, sexual battery and sexual abuse of minors, which lasted for 25 years.

Another lawyer, Dean Armstrong, said they were representing 37 women and that number would likely grow.

Natacha is one of them.

"Seeing his obituary just over a year ago triggered such a huge emotion," she told reporters, without giving her last name. "I could not believe that this monster had gotten away with his crime."

According to a BBC documentary which aired on Thursday, Harrods failed to intervene and helped to cover up abuse allegations during Al Fayed's ownership between 1985 and 2010.

He always denied the accusations.

Lawyer Maria Mulla said once female employees were selected for jobs like secretary or private assistant, they would undergo medical examinations, such as cervical and ovaries screenings.

"If the women would query why the tests were necessary, they would be told...he wants to make sure that you are clean," Mulla said.

Workers were threatened if they tried to complain about the abuse, she said.

Harrods said it was "utterly appalled" by the allegations.

"These were the actions of an individual who was intent on abusing his power," Harrods said in a statement. "We also acknowledge that during this time his victims were failed and for this we sincerely apologise."

Al Fayed sold Harrods to the investment vehicle of the Qatar royal family in a deal reported to be worth around 1.5 billion pounds ($2.3 billion) in 2010.

The department store said it is now a "very different organisation".

'Toxic, unsafe'

Several media organisations had exposed allegations of sexual abuse against Al Fayed in the past, including Vanity Fair in 1995, ITV in 1997 and Channel 4 in 2017. Many of the women only felt able to speak publicly after he died last year.

In 2009, prosecutors decided not to charge Al Fayed over a claim he sexually assaulted a 15-year-old girl in his store, saying there was no realistic prospect of conviction.

"Since new information came to light in 2023 about historic allegations of sexual abuse by Al Fayed, it has been our priority to settle claims in the quickest way possible, avoiding lengthy legal proceedings for the women involved," Harrods said.

A process for those who wish to claim compensation is available for any current or former Harrods employees.

Armstrong said Harrods was aware of Al Fayed's behaviour way before 2023 and should have acknowledged it earlier.

Lawyers said victims deserved justice, and that they would pursue a civil case against Harrods because of its "collective corporate responsibility" for what happened.

"Meaningful accountability means having a proper voice and having the ability to tell your story," Armstrong said.

Born in the Egyptian city of Alexandria, Al Fayed began his career selling fizzy drinks and then worked as a sewing-machine salesman. He built his family's fortune in real estate, shipping and construction, first in the Middle East and then in Europe.

Al Fayed spent 10 years trying to prove Princess Diana and his son Dodi were murdered when their car crashed in a road tunnel in Paris in 1997. His claims were unsupported by any evidence, according to the inquest into Diana's death.
