A Chinese PhD student who drugged and raped 10 women asked to be chemically castrated in an attempt to avoid going to prison.
Zhenhao Zou, 28, was yesterday jailed for a minimum of 22 years for the vile attacks during his time studying at University College, London.
Following his conviction in March, detectives revealed they had evidence relating to suspected attacks on another 50 women in the UK and China after uncovering a sickening collection of trophy videos kept by the engineering PhD student as a souvenir.
Now a further 24 victims have come forward saying they were raped by Zou while he was studying in the UK. The fiend filmed some of his victims helpless and stupefied in sick home videos that he kept of his attacks.
Inner London Crown Court heard that Zou had offered to be chemically castrated to avoid a life sentence.
