A German court ordered Friday that a man who allegedly worked as a bodyguard for Osama bin Laden must be returned after his deportation to Tunisia, saying the expulsion was illegal as he risks torture there. "This afternoon's court decision shows the deportation to be grossly illegal and infringing on basic principles of the rule of law," the administrative tribunal in Gelsenkirchen said in a statement, adding that it "must be reversed".
Judges said authorities had failed to reveal to them the time of the flight, meaning a ruling blocking the expulsion only arrived when the plane for Tunis was already airborne.
Even then, the court added that authorities "knowingly" defied the order by completing the transfer to Tunisian security forces, who immediately placed the deportee under arrest.
The 42-year-old, identified by German authorities only as Sami A. and by Tunis as Sami Idoudi, had lived in Germany for more than two decades, but outrage over his presence grew in recent months as Germany cracks down on failed asylum seekers.
He had previously successfully argued against his deportation, saying he risked being tortured in his homeland.
The Gelsenkirchen court ruled against the deportation late Thursday, upholding the assessment that the suspect potentially faced "torture and inhumane treatment". However the decision only reached federal authorities - by fax - on Friday morning, after Sami A.'s flight to Tunisia had taken off, DPA news agency reported.
Considered a security threat over his suspected ties to Islamist groups, Sami A. has for years had to report to police but was never charged with an offence.
He has always denied being the former bodyguard of late Al-Qaeda leader bin Laden, the mastermind behind the 9/11 attacks on the United States.
Judges in a 2015 terror case in the German city of Muenster however said they believed Sami A. underwent military training at an Al-Qaeda camp in Afghanistan in 1999 and 2000 and belonged to bin Laden's team of guards.
German authorities first rejected Sami A.'s asylum request in 2007 but prosecutors' efforts to expel him were repeatedly blocked by courts citing the danger of torture in Tunisia.
