Remember this from 2019?
Over 1,600 children disappeared from asylum centers in the Netherlands over the past 4.5 years, NRC reports based on figures from the central agency for the reception of asylum seekers COA and Nidos, the organization that has custody of all unaccompanied foreign minors in the Netherlands. These kids left the asylum centers and their current whereabouts are unknown, the newspaper writes.
There are signs that some missing child asylum seekers have ended up in detrimental situations where they may be subject to exploitation, the two organizations told the newspapers. In many cases, missing children left to join family or friends in Germany, Belgium or France. Nidos and the COA told NRC that it is “always worrying” when a child disappears from a shelter.
