Police source says extent of Zhenhao Zou’s violence against women could be worst seen in Britain

A PhD student who charmed women so he could drug, video and attack them has been convicted of raping 10 women in London and China, with police fearing he may have 50 more victims.

Zhenhao Zou, 28, was convicted by a jury at Inner London crown court on Wednesday, after more than 18 hours of deliberations.
