More than 400 alleged victims have so far contacted the legal team working on a case against late Egyptian billionaire Mohamed Al Fayed, accused of sexual abuse and rape, lawyer Dean Armstrong said Thursday.

A BBC documentary in September revealed that Al Fayed, who died last year aged 94, sexually abused female staff at his London department store Harrods, forcing them to undergo medical tests and threatening consequences if they tried to complain.

“The magnitude of the abuses perpetrated by Al Fayed and facilitated by those around him, sadly, continues to grow,” Armstrong said at a news conference in London.

Al Fayed always denied similar allegations raised by other reports before his death. Harrods did not immediately respond to a request for comment on the lawyer’s comments.

The store apologized, said it was “horrified” by the allegations and launched a process for any current or former Harrods employees who wish to claim compensation.

Another lawyer, Bruce Drummond, said the more than 400 claims have been filed by women from around the world, mostly from Britain but also from the United States, Australia, Malaysia, Spain, South Africa and other countries.
