Earlier this year, Chinese student Zhenhao Zou was jailed for 24 years for drugging and raping ten women in the UK and China. He has been described by police as one of Britain’s “most prolific sexual predators”. After his trial, detectives said they feared he may have attacked 50 more women – many of whom are yet to be identified. Following connections on Chinese social media, reporter Wanqing Zhang from the BBC’s Global China Unit has been speaking exclusively to several of Zou’s victims, and a translator who has helped them, revealing shocking details about his crimes.
