‘Incredibly dangerous’ sex offender Chao Xu Jailed – as police say there could be hundreds more Victims

Xu admitted 24 offences including rape, drugging victims and upskirting.

An “incredibly dangerous” sex offender who drugged his victims and installed spy cameras around his home has been jailed for life with a minimum term of 14 years – as police appeal for hundreds more potential victims to come forward.

Chinese national Chao Xu, 33, has been described by police as “one of the most prolific offenders ever uncovered” by the Metropolitan Police.

Xu, who was a law postgraduate student at the University of Greenwich in London between 2015 and 2016, ran his own recruitment business and targeted victims at networking events at his home.

He invented his “Spring of Life” cocktail, a mix of alcohols and Chinese herbal medicines, to sedate guests, and planted spy cameras in items including air fresheners, sanitary packaging and speakers.

Police found thousands of pictures and videos, with some showing unconscious or incapacitated victims in his flat in Greenwich, south-east London.

Xu, who is from China but is believed to have been living in the UK since 2013, also covertly filmed women on their daily commutes at stations such as London Bridge in so-called upskirting incidents.

He pleaded guilty to 24 sex offences between 2021 and 2025 at Woolwich Crown Court in August relating to six victims, with two charges relating to a seventh woman left to lie on file.

Xu admitted four counts of rape, eight counts of assault by penetration, four counts of sexual assault, four counts of voyeurism, two counts of administering a substance with intent and two counts of operating equipment beneath the clothing of another without consent (commonly known as upskirting).

He said all of the sexual assault victims were Chinese women, aged between 18 and 30, while the voyeurism victims are also young females but of different ethnicities.

He added that there will be women who may not know they are victims of his crimes, as they may have been drugged by Xu.

Detectives were alerted to Xu’s crimes after he held a networking event in Greenwich in June.
