- 27 51. It should be added that the CPT’s delegation received many complaints from immigration detainees that very little or no information had been provided to them about their situation and the procedures applied to them. The distress and uncertainty due to the lack of information was particularly acute at the Drepanos Camping site. The CPT wishes to recall the recommendation made in this context in the 1999 visit report (cf. CPT/Inf (2001) 18, Part II, paragraph 44, third indent). 52. In previous reports, the CPT stressed that it would be in violation of both national and international legal obligations for persons to be returned to a country where there are substantial grounds to believe that they would run a risk of being subjected to torture or to inhuman or degrading treatment or punishment (cf. CPT/Inf (2001) 18, Part I, paragraph 97). The CPT has been reassured by both the responses of the Greek authorities and the information received during the 2001 visit from organisations active in the domain of refugees that, once a person files an asylum application, the risk of that happening is small. 53. However, the CPT has continued to receive information about alleged "informal" - including group - deportations to Turkey (cf. CPT/Inf (2001) 18, Part II, paragraph 46). The Committee has been led to believe that, in such cases, the foreigners concerned were deprived of procedural safeguards and were removed from Greece without using recognised border crossings; further, on occasion, their lives might have been put at risk (e.g. by being made to cross a river under precarious conditions). In the CPT’s view, such removals could well amount in many cases to inhuman or degrading treatment. In this connection, the CPT has taken note of the bilateral readmission agreement signed on 8 November 2001 between Greece and Turkey10. The CPT trusts that this has brought informal deportations to an end; it would like to receive detailed information on the implementation of the bilateral readmission agreement. 10 Protocol for the implementation of Article 8 of the Agreement between the Government of the Hellenic Republic and the Government of the Republic of Turkey on combating crime, especially terrorism, organised crime, illicit drug trafficking and illegal migration.
