Singapore: In a first-of-its-kind case reported in Singapore, a 40-year-old woman living as a man, was sentenced to 10 years in jail yesterday for sexually assaulting a teenager multiple times for two years.

Zunika Ahmad is biologically female but lived as a man for several years and married two women. She is also registered as the father of a teenage daughter.

Ahmad's sentencing comes less than two weeks after Singapore's apex court overturned her acquittal, quashing the decision of a High Court judge who ruled that only a man can be prosecuted for the offence of sexual assault of a minor.

Her family and the 13-year-old victim were in the dark about Ahmad's "true identity" until her arrest, after which she was diagnosed with gender dysphoria, it was reported.

Ahmad was cleared of sexual assault charges in April, after a High Court judge ruled that the particular section of the law that she was charged under "does not cover women as offenders".

Though the pair were in a relationship and the girl had consented, they were still illegal as the age of consent in Singapore is 16.
