CAT/C/FIN/CO/5-6 appropriate time, so that the Parliamentary Ombudsman may act as the national preventive mechanism. Detention and ill-treatment of asylum-seekers, irregular immigrants and other aliens 17. The Committee is concerned about information regarding the frequent use of administrative detention with regard to asylum-seekers, irregular immigrants, unaccompanied or separated minors, women with children and other vulnerable persons, including those with special needs, as well as with their numbers, the frequency and the length of their detention. In addition, the Committee is concerned that the Aliens Act allows for preventive detention not for a crime already committed but if a person is suspected of the possibility of committing a crime (arts. 11 and 16). The Committee recommends that the State party consider alternatives to the frequent detention of asylum-seekers and irregular immigrants, including minors and other vulnerable persons, and that it establish a mechanism to examine the frequent detention of such persons. It recommends that the State party consider increasing the use of non-custodial measures, use detention as a last resort and ensure that administrative detention of unaccompanied children is not practised. The Committee requests the State party to ensure that the Body of Principles for the Protection of All Persons under Any Form of Detention or Imprisonment be applied to asylum-seekers in administrative detention. In addition it would appreciate receiving information on the number of asylum-seekers and irregular immigrants in detention, how frequently they are detained and the average length of their detention. 18. The Committee is concerned at the conditions and length of detention of asylumseekers and irregular immigrants at the detention unit for foreigners at Metsälä and the lack of legal safeguards regarding the length of detention. It is also concerned that such persons are detained not only in the Metsälä detention centre, which has a small capacity, but also in police and border-guard detention facilities which are not suitable for holding persons detained under legislation on aliens. The Committee is concerned that men and women are held together in such facilities, that children are held with adults when families with children are placed in migration-related detention and that a total of 54 children were detained in 2010 under the Aliens Act (arts. 2 and 11). The Committee recommends that steps be taken to increase the capacity of the Metsälä detention centre or establish a new detention centre for foreigners. It also recommends that the State party review the detention, including length, of asylumseekers, irregular immigrants and other foreigners in the Metsälä centre as well as in police and border-guard detention facilities, provide them with fundamental legal safeguards and set up a complaints mechanism regarding conditions of detention, and use non-custodial measures. 19. The Committee is also concerned at allegations concerning the rise in physical and psychological ill-treatment of asylum-seekers and irregular immigrants, including their harsh treatment by the police and other law enforcement authorities (arts. 10, 11 and 16). The Committee recommends that the State party ensure that specialized training and internal guidelines for police, border guards and other law enforcement authorities make them aware of their obligations under human rights and refugee law so that they may treat asylum-seekers in a more humane and culturally sensitive manner and that perpetrators of ill-treatment are investigated, prosecuted and convicted.
