Mohamed Al Fayed was an Egyptian billionaire businessman who owned Harrods in London, one of the world's most famous department stores. He also owned the Ritz Hotel in Paris and Fulham Football Club, and famously courted the British Royal Family.

But a new BBC investigation reveals he's also accused of being a serial rapist and abuser of women in his employment.

Katya Adler speaks with Cassie Cornish-Trestrail and Keaton Stone about Al Fayed's alleged crimes and we hear first-hand testimony from the women speaking out.

Warning: this conversation contains details some may find distressing.

You can hear the full investigation on the podcast World of Secrets, Season 4: Al Fayed – Predator at Harrods.
