A/HRC/13/42* page 31 Government offices, automobile repair shops, schools, farms and even the basement of the upscale Galerias Pacifico in downtown Buenos Aires.79 The largest secret detention centres were the Navy Mechanics School (Escuela de Mecanica de la Armada) and the Club Atlético, a federal police facility, both in very visible Buenos Aires locations; the Campo de Mayo army base and Vesubio, a former summer residence, both in the province of Buenos Aires; La Perla, a military base in Córdoba Province; and La Cacha, located within the offices of the penitentiary.80 Notwithstanding the fact that it was estimated that these facilities held some 14,500 detainees, the military authorities repeatedly denied the existence of secret detention centres.81 64. In Chile, torture methods were routinely practiced on all detainees held in secret facilities. Some of the secret detention facilities mentioned in the report of the Chilean National Commission on Truth and Reconciliation were Tejas Verdes, Cuatro Alamos, Londres No. 38, José Domingo Cañas, Villa Grimaldi, The Discotheques or La Venda Sexy, Casa Cajón del Maipo, la Firma, Simón Bolívar con la calle Ossandón, Nido 20 y Cuartel Venecia. According to information provided by the Government, the report of the National Commission on Political Prison and Torture of 2004 indicated that there were 1132 places used for purposes of detention throughout the country.82 The sites themselves were equipped with permanent installations for applying enhanced methods of interrogation and special personnel trained to use them. The guards were not the same as the officers who were in charge of interrogations, although the latter could take part in inflicting torture and indeed did so directly.83 For years there were secret detention sites to which officials of the judicial branch had no access. The courts did not act to remedy this unlawful situation or even to condemn it, despite continuous claims made in habeas corpus appeals.84 This was compounded by the fact that, during the Pinochet regime, the authority to “arrest” included the authority to order solitary confinement. This, together with the lack of provisions requiring the disclosure of the place where a person was being held, facilitated the use of secret detention.85 79 According to the information provided by the Government, there are no records indicating that Galerias Pacifico was used as a secret detention centre. 80 See also the reports on clandestine detention centres in the annual report of the Working Group on Enforced or Involuntary Disappearances (E/CN.4/1492), paras. 48-50.
