A 44-year-old Hong Kong man was jailed for 12 years by the High Court on Wednesday after earlier being found guilty of rape and an additional charge of administering drugs to obtain or facilitate an unlawful sexual act.

Man Yiu-fai, a self-proclaimed health consultant, gave a drink laced with a date-rape drug to a German tourist, then 23, who went to his clinic in Mong Kok for treatment for pain in her pelvis on May 31, 2015. When the woman woke up, she found that Man was raping her.

The police later arrested Man at his home in Tseung Kwan O, Sing Tao Daily reported.

The incident took place when Man was out on bail on a charge of  allegedly administering drugs to obtain or facilitate an unlawful sexual act and committing an indecent assault on a 22-year-old local woman, whom he came to know in Mong Kok during the Umbrella Movement, in 2014. However, Man was acquitted of those two charges because of  technical issues.

With a master’s degree in Chinese and herbal medicine from mainland China, Man claimed to be a master of natural healing, but he was never registered as a practitioner in Hong Kong, Apple Daily reported.

During the investigation, Man told the police that he had put  ayahuasca, a hallucinogenic drug, into a drink for the German woman and then had sex with her but did not ejaculate.

Mr Justice Michael Stuart-Moore slammed the married man for showing no regret and telling lies, noting that he raped the woman without a condom while recording the crime with a smart watch.
