The high-end London department store, Harrods, said Thursday that it is 鈥渦tterly appalled鈥� by allegations of abuse 鈥� including rape 鈥� perpetrated by its former owner, the late billionaire Mohamed Al Fayed.

More than 20 female ex-Harrods employees have accused Al Fayed, who died last year at age 94, of sexually assaulting them, according to an in-depth BBC investigation. One said she was assaulted when she was 15 and Al Fayed was 79. Harrods acknowledged that Al Fayed was 鈥渋ntent on abusing his power wherever he operated.鈥�

The alleged assaults are said to have taken place at a wide range of locations, including Al Fayed鈥檚 luxury apartment building in London, the Ritz hotel in Paris, which Al Fayed owned, and a Parisian villa that Al Fayed rented called Villa Windsor, known for being the main residence of the Duke of Windsor, a former British king, and his wife, for decades.

Al Fayed鈥檚 son, Dodi Fayed, died in 1997 along with Princess Diana in a high-speed car crash in Paris.

Numerous women interviewed in the BBC investigation described instances of being invited to an apartment block owned by Al Fayed after finishing late shifts at Harrods. They said they would be invited there under the pretense of safety, being allocated their own apartment to stay in to avoid traveling home late at night. Once there, the women said they would be called up to Al Fayed鈥檚 own apartment, where he would greet them in a silk robe and force himself onto them.

Thirteen women said they were sexually assaulted at Al Fayed鈥檚 apartment block, including four who said they were raped there.

One woman, Sophia, said she was working in the Harrods women鈥檚 clothing department when Al Fayed approached her and offered her a job in his office. A few days after she started the new job, Sophia said that Al Fayed began to 鈥渂ear hug鈥� her, then tried to kiss her.

In a separate incident, Al Fayed invited her over to his London apartment, where she said he pushed her onto the sofa and then forced himself on top of her.

鈥淚鈥檓 strong and I starting kicking him, and I kicked him off really hard,鈥� said Sophia, who the BBC documentary identified by her first name only. 鈥淚 thought 鈥榟e鈥檚 going to rape me鈥�.鈥�

鈥淚t was a horrible, horrible nightmare,鈥� she continued. 鈥淚t was really hard to get out of it. I can鈥檛 explain how it ground me down every single day.鈥�

Many of the women who were allegedly assaulted by Al Fayed also said they worked on the Harrods shop floor before being approached by the chairman.

鈥淲e all stood and watched each other walk through that door thinking 鈥榶ou poor girl, it鈥檚 you today鈥� and feeling utterly powerless to stop it,鈥� one woman using the pseudonym Alice said. She said she was 16 years old when she was assaulted by Al Fayed.

Another woman told the BBC that she was assaulted by Al Fayed in the boardroom of Harrods in May 2008, when she was 15 years old. She reported it to police, but charges were not brought against Al Fayed. He denied the allegations at the time.

Former Harrods employees told the BBC that Al Fayed鈥檚 treatment of women was known throughout the department store, with one former department manager saying that it 鈥渨asn鈥檛 even a secret.鈥�

鈥淚 knew and I think, if I knew, everybody knew. Anyone who says they didn鈥檛 they鈥檙e lying,鈥� the former department manager Tony Leeming said.

鈥淚t was a joke and it was laughed about,鈥� Leeming said. 鈥淚t was like 鈥極h you know, this person鈥檚 going to be a manager in five minutes because she鈥檚 gone up to Al Fayed鈥檚 office. Ha ha ha.鈥欌��

鈥淟ooking back on it now it鈥檚 pretty repellent, he continued.

Harrods apologized to victims in a statement, adding that 鈥渢he Harrods of today is a very different organization to the one owned and controlled by Al Fayed between 1985 and 2010.鈥�

鈥淲e are utterly appalled by the allegations of abuse perpetrated by Mohamed Al Fayed,鈥� the company said. 鈥淭hese were the actions of an individual who was intent on abusing his power wherever he operated and we condemn them in the strongest terms. We also acknowledge that during this time as a business we failed our employees who were his victims and for this we sincerely apologize.鈥�

Harrods said that last year 鈥渘ew information came to light鈥� about historic allegations of sexual abuse perpetrated by Al Fayed. Since then, it said, 鈥渋t has been our priority to settle claims in the quickest way possible, avoiding lengthy legal proceedings for the women involved. This process is still available for any current or former Harrods employees.鈥�
