Police said they would investigate whether any other people should be pursued on criminal charges following the abuse allegations against former Harrods owner Mohamed Al Fayed.
The Metropolitan police urged anyone who has not yet come forward to do so and said it would also investigate past complaints.
Police said they had identified 19 recorded suspected crimes involving Al-Fayed that were reported to the Metropolitan police between 2005 and 2023. The crimes are alleged to have been committed between 1979 and 2013.
It comes after the BBC last week heard testimony from more than 20 former Harrods employees who allege they were sexually assaulted or raped by the billionaire.
Al Fayed, who died in 2023 aged 94, took over the luxury department store in 1985 and sold it in 2010.
Of the 19 complaints, three were allegations of rape, 15 were sexual assault and one involved human trafficking.
The Metropolitan police said it had made complaints to the Crown Prosecution Service (CPS) on five occasions between 2005 and 2023. No further action was taken in relation to any of the allegations.
“We are thoroughly investigating all existing allegations reported against Mr. Al Fayed to ensure that no new investigative leads are opened,” the company said.
Police officials said they were in contact with other groups, including lawyers representing the suspects reported in the media.
The Metropolitan police said they were unlikely to convict Al Fayed himself but that “full investigations will be required to determine whether other individuals may be charged with criminal offences”.
“It’s really important that victims come forward and know that if they have allegations they haven’t reported before, they can report them and they will be taken seriously,” Commander Steven Clayman said.
The company said it has a dedicated team in place and understands many people have been seeking answers for many years.
Meanwhile, Harrods managing director Michael Ward said on Thursday that Al Fayed “presided over a harmful culture of secrecy, intimidation, fear of retribution and sexual misconduct”.
“Harrods has let our colleagues down and for that we deeply apologise,” he said in a statement.
“We have all seen survivors bravely speak out about the horrific abuse they suffered at the hands of Mohamed Fayed, the former owner of Harrods,” he said.
“While it is true that rumors have circulated publicly about his behavior, no allegations or allegations have ever been made against me by police, Child Protective Services, internal channels or otherwise.
“If that was the case, I would of course act immediately.”
“Harrods today is a separate business from the Harrods under (Mr Al Fayed’s) ownership,” he said, adding that the company had started a settlement process for victims.
Last week, the BBC released a documentary and podcast, “Fayed: The Harrods Predator,” which brings together testimonies from more than 20 women, including five who say they were raped by Al Fayed.
According to former employees, Al Fayed would regularly walk through Harrods’ vast sales floors, spotting young women he found attractive and then promoting them to work in his office upstairs.
Since the allegations were made public, many more former Harrods employees have contacted the BBC to say they were assaulted by Mr Al Fayed.
The investigation also found evidence that Harrods failed to intervene in allegations of abuse during Mr Fayed’s time as owner.
