The Swedish Migration Board were skeptical of 4,200 asylum cases of migrants without papers claiming to be children, so sent the names to forensic experts to determine how old they were.
The company, Rättsmedicinalverket, is now sifting through the files and having tested 581 people, 447 of them have been medically proven to be 18 years old or older.
Of the 4,200 ordered by the migration officials, a massive 96 per cent of them were men.
They will be subjected to rigorous tests by medical professionals to establish whether or not they are children as they claimed when arriving in Sweden. The tests are carried out in two stages – an x-ray of the wisdom teeth and an MRI scan of the knee joint.
Doctors forensically analyse the results and form an opinion of the age before sending it back to the migration board.
Ann Lemme, spokeswoman Rättsmedicinalverket, said: ‘The results do not say exactly how old a person is, but is an assessment whether the person is over or under 18 years.’
‘We expect to be able to manage our opinions at a faster pace now that our initial quality inspection and system review is conducted.’
So far, 18 female asylum seekers and 563 male asylum seekers have been tested. The results revealed 442 of the males are adults as well as 17 of the females. This means only 134 are actually boys and just one is a girl.
