Trafficking in minors for exploitation in criminal activities is a form of human trafficking that is generally not well-recognised and understood by frontline actors. This paper, based on empirical data from frontline actors, shows that this is also the case in the Netherlands. Moreover, the Dutch ethnicised understanding of the phenomenon, which is conceptualised as a ‘Roma’ problem, further obfuscates the identification of these trafficking cases, leading to a blind spot for victims of other ethnicities and differential treatment of itinerant ‘Roma’ victims compared to Dutch and resident victims. It also shows that there is a gender bias among frontline workers, with girls being more readily perceived as victims than boys, and interventions in the girls’ cases geared towards protection, whereas boys were seen as ‘little rascals’ that should be punished. The paper concludes that a focus on indicators of the phenomenon, rather than on victim profiles, could improve this situation and help frontline actors take more transparent as well as ethnic- and gender-neutral decisions.
