This is happening all over the globe. For example in Nepal, Muslim men (especially migrants from the Indian state of Bihar) prey on vulnerable girls. They convert these women and then marry them. Once the marriage is done, using these women they recruit teenage girls, often 15-16 years of age. They promise jobs as housemaids and shop assistants in India. Once these girls reach India, they are sold to brothel owners. For the Muslims, infidel women are just commodities.
I am also from Nepal, and recently I have noticed an increase in similar incidents. Earlier they used to target the lower caste girls. But now they are increasingly preying on ethnic and higher caste girls. Unfortunately, currently a pro-Muslim government is in place in Nepal.
