An unemployed Hong Kong man who forced his girlfriend’s underage daughter to have sex with him while her mother was outside on the balcony of a studio flat was jailed for six years and nine months by a court on Wednesday.

Prosecutors revealed that the man, now 63, had told the 15-year-old last year that he would evict her mother from their home if she refused sexual intercourse while her mother stood outside, her view obscured by a wardrobe.
