Officials in Dordrecht are worried about a group of about 800 youths and young adults who appear to live under the radar, the Telegraaf said on Tuesday.

The group, ranging from ages 15 to 27, is not in any kind of education, has no job, is not receiving any benefits and is not registered to an employment agency. Officials fear they might be working in the criminal circuit, as they are not attending school or college and don’t have basic qualifications, the paper said.

Over the next two years, officials will be making an effort to get more insight into the ‘phantom group’. They plan to contact all 800 to get an idea of what they’re doing and how they’re making a living. They’ll also encourage them to go back into education or find a job.

Engaging the ‘phantom group’ is part of the regional action plan to combat youth unemployment. In Dordrecht, almost 600 youths are on welfare and about 550 are receiving unemployment benefits.

More than 2,000 Dordrecht residents under 27 years old have left school without basic qualifications.
