CAT/C/LIE/CO/3 Treatment of persons deprived of their liberty 23. The Committee is concerned with the practice by the National Police of covering the eyes of apprehended persons considered extremely dangerous and violent with black goggles and, until 2007, of covering the heads of such apprehended persons with a bag, and that such practices are justified on grounds of protecting the identity of the suspect and protecting the law enforcement officers. While appreciating that the practice of black goggles has been used only once in 2007 and once in 2008 by the State party officials, the Committee notes that the practice is still allowed by law and that it may still be used on exceptional occasions. The Committee remains concerned that such a practice often makes the prosecution of torture virtually impossible (arts. 2, 11 and 16). The State party should ensure that the practice of covering the head or eyes of suspects by the National Police is abolished in law and in practice. The State party should introduce alternative measures which respect the inherent dignity of suspects while ensuring the safety and protection of police officers. 24. The Committee notes with appreciation that the practice of ensuring psychological care for inmates at the Vaduz National Prison through visits by staff of the Therapeutic Services Division of the Office of Social Affairs has been reintroduced as of 2010, pursuant to the recommendation by the Corrections Commission. In view of the absence of a fulltime nurse or other medical personnel in the prison, the Committee furthermore expresses appreciation that the State party has initiated a process of assessing and evaluating the possibility of ensuring that medicaments are provided solely by medical personnel and not by corrections officers (arts. 11 and 16). The Committee recommends that State party considers the appointment of a parttime nurse or other medical staff member at Vaduz National Prison, with a view to ensuring that medicaments are provided by medical personnel only. Interrogations 25. While the Committee notes that all police interrogations have to be documented in writing, it is concerned that, at present, police interrogations are neither audio nor video recorded, with the exception of interviews with victims of sexual crimes (arts. 2, 11, 12 and 16). The State party should further improve interrogation rules and procedures of the National Police by amending the Code of Criminal Procedure with a view to introducing audio- and, preferably, video-recording of all police interrogations and questioning as part of the State’s parties efforts to prevent torture and ill-treatment. Investigations into allegations of ill-treatment 26. The Committee notes with concern that some allegations of excessive use of force, tight-fitting handcuffs and verbal abuse by police at the time of apprehension were reported in 2007 by the European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment of the Council of Europe. In this respect, while noting the establishment in the same year of a special unit in the National Police tasked with investigating allegations in respect of certain serious criminal offences against police officers and other State officials, the Committee emphasizes the importance of the independence of the body carrying out such investigations (arts. 11, 12 and 16). The Committee strongly recommends that all allegations of ill‑treatment by police should be investigated promptly and impartially by independent bodies and not by other members of the police force. 8
