Harian Metro also reported that a 15-year-old girl was forced to be her stepfather's sex slave after he threatened to kill her if she told on him.

However, the matter was exposed after the girl was discovered to be four-months' pregnant.

The man had allegedly raped her thrice since last August, it was reported.

He would force himself on her when her mother was away or asleep.

According to a police source, in the first incident, he sneaked into the girl's room while she was asleep and after raping her, threatened to kill her if she reported the matter.

Two months later, he raped her again when she was baby-sitting her six-year-old sibling while her mother was out shopping.

When the girl later developed a severe pain in her stomach and went to her aunt for a traditional massage, it was discovered that she was pregnant.
