Tunisia has confiscated the passport of a man who once served as Osama bin Ladens bodyguard to prevent him returning to Germany, spokesman of Tunisias anti-terrorist judiciary body Sofian Sliti, said on Friday. Germany deported Sami Aidoudi last month but a German court on Wednesday demanded his return. Tunisian authorities initially detained Aidoudi after Germany deported him last month. It released him after two weeks for lack of evidence but has barred him from leaving the country pending the outcome of a probe. "The investigation is ongoing... His passport has been confiscated by a court (in case he gets charged)," said Sliti. "If there was a request from German authorities (to Tunisia) to hand him over it should come via diplomatic channels," he added, without elaborating. A spokesman for the German government said Berlin was in constant contact with Tunis via its embassy there and would continue to discuss the case. Aidoudi - referred to only as Sami A. in Germany – applied unsuccessfully for asylum there in 2006. German Interior Minister Horst Seehofer, who has taken a tough line on immigration, accused him in May of having been bin Ladens bodyguard and said he should be deported. Aidoudi always denied the allegation but was arrested in June and deported a month later on July 13. Germanys interior ministry later denied opposition accusations that it had pressured authorities in the state of North Rhine-Westphalia to accelerate the deportation.
