Moment police arrest rapist Zhenhao Zou
When he was arrested in January 2024, serial rapist Zhenhao Zou was living on the 39th floor of an expensive block of London flats with views across the city.
Police found his bedroom had been equipped with hidden cameras and discovered a wardrobe stocked with alcohol, ecstasy and an industrial chemical that the human body turns into the "date rape" drug GHB.
Police were able to charge him with multiple assaults on women in both the UK and China - including the rapes of women who have never come forward and have never been identified.
Detectives say they fear he may have raped as many as 50 more women. "This man may well turn out to be one of the most prolific sexual predators that we've ever seen in this country," Commander Kevin Southworth, from the Metropolitan Police, told the BBC.
Southworth added: "Such is the insidious nature of this offending, I think there is a possibility that many more victim survivors may not even know that he has raped them."
Detectives are asking any woman who may have spent any time alone with Zou - whether in China or in the UK - to come forward.
