But it seems this practice of forcing another human being to work without their consent still goes on in what is called a 'hidden crime'.
The UK couple who trafficked a 10-year-old girl to the UK have been convicted. She was repeatedly raped and kept as a domestic servant for nearly a decade. The victim was only found after trading standards officials visited their home investigating allegations of illegal activity.
Details of the victim's ordeal only emerged after she was taught sign language, enabling her to be interviewed by police. Thankfully, the bright girl is now being supported, living a good life, and has achieved her potential. But others aren't so lucky, if you can call it that.

I know. We don't want to face more bad news. Why can't we live our own lives and ignore what goes on elsewhere? But this could be happening near you. If everyone is aware of this shocking crime, perhaps more can be done to rescue the unseen sufferers so they can share the wonders of our modern world.
I will hold them in my prayers.
