FORGOTTEN Administratively detained irregular migrants and asylum seekers ii. Findings During our visits at the Detention Centers, we interviewed detainees who have been registered as adults but claimed that they were minors.

In the cases where our Organization brought up the issue, the detainees were referred to the hospital for skeletal age measurement43, which is the main method of age determination in practice.

However, at the First Reception Center he was recorded as born on 1/1/1997. We note that, at his registration form, there are the signatures of 43 «The age determination through specific medical examinations is currently contested by the international scientific community, as divergences are observed between the skeletal age depicted in the x-rays and the biological age –divergences that might increase in relation to the age and the tribe of the person», Greek Ombudsman, The issue of age assessment of unaccompanied minors, page. 4, October 4 2014, available at: www.synigoros.gr/resources/porisma_diapistosianilikotitas-asynodefton-anilikon.pdf (September 5 2016). 69
