Iñaki Garcés Beitia was detained for the first time between 1987 and 1990. In 1998 he was again arrested by the Civil Guard in Vitoria and reported his torture during the incommunicado detention. The National Court sentenced him to 25 years in prison for damage to the military base of Arara (Álava), for possession of explosives and for belonging to ETA.

He spoke, inter alia, of the rights lost by prisoners and their families in the context of the pandemic. Here you can read the report and here Garcés' letter is complete.
