4.  The applicant was born in 1949 and lives in Gdańsk, Poland. 5. On 16 July 2004 the applicant was arrested on suspicion of robbery. On 17 July 2004 the Gdańsk District Court (Sąd Rejonowy) ordered that the applicant be remanded in custody until 16 October 2004. It found that there were reasonable grounds – in particular, evidence from witnesses – for suspecting him of the offence charged. The court further noted that the applicant was liable to a statutory maximum sentence of at least 12 years’ imprisonment. It also found that there was a risk that the applicant might tamper with evidence. 6. On 11 October 2004 the Gdańsk District Court prolonged the applicant’s detention until 16 January 2005. It considered that the reasons for keeping him in detention were still valid and the need to secure the proper conduct of the investigation justified holding him in custody. It referred to the likelihood of a severe sentence of imprisonment being imposed on the applicant. It also found that there was a risk that the applicant might tamper with evidence, given the nature of the charges against him and the fact that he had acted with other co-accused. 7. The applicant’s detention was subsequently prolonged by the District Court on unspecified dates. The courts’ decisions were based on Article 258 § 1 of the Code of Criminal Procedure, which lists grounds for pre-trial detention, such as, the risk that an accused will abscond or go into hiding or a justified fear that an accused will attempt to induce witnesses or co-defendants to give false testimony or to obstruct the proper course of proceedings by any other unlawful means. 8. On 27 October 2005 the Gdańsk District Court convicted the applicant of two counts of robbery and sentenced him to 3 years and 6 months’ imprisonment. The applicant appealed. 9. On 26 September 2006 the Gdańsk Regional Court (Sąd Okręgowy) upheld the impugned judgment. 10. The applicant did not lodge a cassation appeal. 11.
