From the article:
...Her captors told her to never speak to police, that officers would beat her. She stayed tight-lipped until she was allowed to call her parents in Egypt, and her father ordered her to go back with her captors...
Father was probably afraid to lose that 30 bucks a month income.
This is a little off topic but folks should read: “I Am Nujood, Age 10 and Divorced”, a true story of a young Yemini girl who was married off by her father to some middle aged guy. Some Muslim family values.
