Due to the extensive reach that Mobile Info Team has with people on the move living across Greece through our Facebook page and WhatsApp hotlines, we predominantly recruited our participants digitally. In order to do this, we set up Facebook ads and boosted them over a period of six months, resulting in individuals reaching out to us to share their past experiences, with the support of translators. Mobile Info Team’s caseworkers also recruited several participants through our hotlines, where individuals who were previously in detention reached out for support with their asylum procedure or their general situation. We additionally spoke with people who attend a local food distribution site, and were provided with a number of testimonies by the Border Violence Monitoring Network (BVMN) pertaining to people’s previous experiences in detention. Our research is based on interviews with people who have been detained in Greece at some point since the beginning of 2021. Whilst our research was focused on the six PRDCs in mainland Greece, and not those held in judicial prisons, we also spoke with people who were held in Korydallos - Greece’s largest prison complex and main maximum security facility - and Nigrita Prison - who were asylum seekers. This provided another layer of understanding with regards to the arbitrariness of detention practices, as well as lack of adherence to asylum laws. In addition, despite many respondents having also been held in police stations or informal detention sites since being in Greece and sharing their experiences in such sites, we remained focused on PRDCs on mainland Greece: Xanthi, Paranesti (Drama), Corinth, Amygdaleza, Tavros (Petrou Ralli) and Fylakio. The distribution of interviews was not equally spread among each centre due to logistical and geographical constraints. As such, our research generated more in depth information on some PRDCs than others. We undertook in-depth interviews with 50 respondents - including 46 who were held in PRDCs - including people from Afghanistan, Algeria, Egypt, Iran, Iraq, Kurdistan, Morocco, Pakistan, Syria and Türkiye, between the ages of 16 and 51 years old. Only one of our interviewees was female, which is somewhat representative of the ratio of males and females held in PRDCs in Greece. Therefore, this research is reflective of the situation in Greece, but does not account for the significant number of women who are also held and experience their detention differently. The interviews were semi-structured, enabling the conversation to be directed by respondents and their specific situations. Our questions were based on access to asylum, legal counselling, information, translation, hygiene conditions, basic facilities, medical and psychological care, access to education or recreational activities, and the practice of protests. Some interviewees shared our contact with friends who had also been in detention, expanding our outreach. All personal information is kept anonymous and no personal details are retained from interviews, to protect the identity of individuals, many of whom remain in precarious situations. Carrying out many of our interviews over the phone resulted in respondents feeling safer to share their experiences in an anonymous manner. Nevertheless, the majority of respondents did not fully understand their situation, the procedures or their rights, and many had experienced extremely challenging circumstances. Therefore, this research draws on personal experiences which may be impacted by trauma, psychological stress and confusion. Several respondents also shared visual data regarding the detention centres that they were held in. Some of these photographs have been anonymously included throughout the report to provide further evidence on detention conditions. In order to support our findings from interviews, we carried out an analysis of our case register, monitoring people’s enquiries regarding detention between 2021 and October 2022. More than 600 case files were analysed and 151 used to create a more general understanding of the types of issues Mobile Info Team’s clients report. 95% of these 151 case files are men. Most of our clients have been detained in Corinth or Amygdaleza. In addition, we spoke with several civil society organisations (CSOs) operating in Greece and gathered information from a variety of online sources - including CPT reports - to gain historical insight into detention practices and perspectives from those who have access to detention facilities. Border Criminologies and BVMN supported us with the research process. 14
