More than 3,000 children and teenagers have gone missing in just one region of Germany after entering the country during the migrant crisis in 2015.
And they have also disappeared off the visa programme known as the Schengen information system which allows them to move freely through-out Europe.
And no one can trace where the youngsters who entered the German state of Bavaria which borders Liechtenstein, Austria and the Czech Republic have gone sparking fears some could have fallen victim to human traffickers.
Nearly 17,000 children and teenagers arrived in Bavaria in 2015 as refugees and migrants without their parents.
Thousands kept travelling without giving notice of their intended destinations.
Now no-one in Europe can accurately record their movements or identify where they are or whether they are in need of shelter.
And while some sources say the children and teens could have moved in with relatives it is unclear where they are.
A local enquiry is currently underway in the region to ascertain what checks need to be put in place to identify the amount of young people who are believed to be travelling on their own.
According to reports, 4,452 teenage refugees who came to Bavaria without their parents were reported missing in 2015.
While only 1,090 reappeared in Germany or Scandinavia.
The German federal government, which is governed by a coalition of the Social Democratic Party of Germany and Christian Unionists groups, has been working with the United Nations Children’s Emergency Fund.
But they are struggling to cope with the amount of unidentified minors who have literally disappeared off the radar with local politician and Member of bavarian Parliament Florian Ritter questioning whether young girls and women have fallen into the hands of pimps and sexual predators.
“The fact is, that by totally losing control of the migrant crisis, Angela Merkel and the EU have failed these children and the people of Europe.
“I have been saying since the start of the migrant crisis that the EU needs to get an urgent grip on this situation; turn back economic migrants and properly document and keep track of genuine asylum seekers for both their own safety, as well as the host communities.”
