26. The below cases are for the purpose of illustration. All persons provided information about their alleged ill-treatment under conditions of anonymity:7 i. Two foreign nationals detained at Corinth PRDC consistently alleged in separate individual interviews that, between six and eight weeks prior to the visit, usually in the late evenings, each of them was individually brought by five to seven police officers to a room used by staff in the administrative compound. Both had either made requests or been in an altercation with another detained person. They both alleged having been subjected to baton blows, kicks or slaps by police officers for some 10 to 15 minutes. One person alleged that he had first been fitted with a helmet with a visor, to prevent him from seeing and to avoid head injuries. During their ordeal, the policemen insulted them and repeatedly made fun of them. ii. Two foreign nationals held at Tavros (Petrou Ralli) PRDC indicated that, on several occasions and in separate incidents, they had been physically ill-treated by custody police officers, after having requested a razor or to be seen by a doctor. One of the two persons notably alleged that, several days before the delegation’s visit, six police officers entered the wing and took him out of his cell, handcuffed him and subjected him to kicks and baton blows. After having pushed him to the ground, two police officers placed their feet on his back and the back of his knee to hold him down while one officer pulled his head back and choked him. In this regard, see also paragraph 13.8 iii. Another detained foreign national alleged that, in October 2023, he was intercepted and apprehended by a vessel of the Hellenic Coast Guard during an attempt to cross by speed boat from Türkiye to Rhodos Island. He complained that, when boarding the coast guard vessel, he was hit with the butt of a rifle by one of two masked coast guard officers who considered him the driver of the speed boat, and he fell to the ground. He alleged that he was then kicked and punched repeatedly by these two coast guard officers, while lying on the ground, and that he fainted when he was kicked in the face by a third official. 27. While taking note of the policy of zero tolerance in respect of human rights violations expressed by the political leadership of the Hellenic Police, the CPT calls upon the Greek authorities to take more vigorous steps to end ill-treatment of foreign nationals deprived of their liberty by the Hellenic Police and the Hellenic Coast Guard under immigration legislation. It should be reiterated on a regular basis to police and coast guard officers that foreign nationals must be treated with respect and that any form of ill-treatment of detained persons – including verbal abuse and racist language – is unacceptable and will be punished accordingly. Further, the authorities should ensure that an effective investigation is carried out into all allegations of ill-treatment. 28. Moreover, at Corinth PRDC, several foreign nationals also complained about alleged informal punishment by police officers, which included instances of disciplinary isolation, forced undressing and removal of mobile phones, in response to incidents of inter-detainee violence, disobedience or repeated requests. For example, one foreign national alleged that two police officers compelled him to fully undress and remain naked in the washroom of his wing for several minutes, as a punishment for being late for lock-up. Another person claimed that he remained for several days in disciplinary isolation in a separate building following an altercation with another detained person, without any disciplinary procedures having been followed. Such alleged informal punishments are clearly inadmissible. The CPT recommends that the Greek authorities ensure that the management at Corinth PRDC acts to prevent that foreign nationals are subjected to the practice of informal punishments. Further, the senior officers at Corinth PRDC should be held accountable for their line-management responsibilities. 7. In this respect, it is incumbent upon each person to lodge a complaint with the competent authorities, as providing the CPT with details of their alleged ill-treatment does not constitute an official complaint. This was made clear to the persons met by the CPT delegation during the visit. 8. The delegation’s request to consult the corresponding CCTV footage was not granted. 11
