Methodology The collection of data on violence in detention centres is done through a consortium of independent voluntary field experts who are part of the BVMN. The accuracy and consistency of testimonies is crucial to BVMN’s mission and therefore strict training, interview templates and guidelines are provided to reporters. The interviews are semi-structured, through standardised, open-ended questions, and designed to enable the conversation to be guided by the respondents’ experiences. BVMN’s reporters are trained to conduct interviews that capture specific details, for example, characteristics of detention staff uniforms, in order to generate verifiable data. Leading questions are avoided, although some questions may be rephrased, with the support of a translator, in order to ensure clarity and total understanding. Internal violence reports are collected both over the phone - for respondents who are not located near BVMN reporters - or in person, at community centres that provide services for people on the move. Testimonies were only taken from people who were in detention at some point since 2020, so as to capture information pertaining to detention practices since the changes in Greek law implemented by the current government. Testimonies are collected anonymously and BVMN does not retain any identifying data on the respondents. All testimonies are taken on the prior understanding that they will not help an individual’s case, and with informed consent. 50 testimonies were collected and analysed for this report, from people who were detained from a period of one day to beyond 18 months in a police station, special holding facility or one of six PRDCs on mainland Greece: Xanthi, Paranesti (Drama), Fylakio, Corinth, Amygdaleza, and Tavros (Petrou Ralli). Over 50% of respondents have been held in at least two detention facilities in Greece since 2020. The majority of respondents were apprehended in Thessaloniki, Athens or in the Evros region. 8
