Disse forbrydelser begås af skruppelløse bagmænd, der får fat i deres ofre ved hjælp af vold eller bedrageri, måske løfter om ærligt, velbetalt arbejde eller trusler både mod ofrene selv og mod deres børn eller slægtninge.
These crimes are committed by unscrupulous people who recruit their victims through violence or deception, perhaps by promising an honest, well-paid job or through threats, directed not only at the victims, but also at their children or relatives.
