Gholam Ghaus Z.

Gholam Ghaus Z. was a German citizen wrongly imprisoned for over four months in the Bagram Theater Internment Facility in Afghanistan.

Der Spiegel reports that the 41-year-old Gholam Z. had taken early retirement, due to medical problems.

Gholam Z. borrowed a relative's car to go on, what a security expert called, his "fatal shopping trip."

According to his version of events, he drove up to the military base on Jan. 4, showed the guard his German passport and was then allowed to pass through several security checkpoints without incident.It reported that German security officials who investigated his background in Germany, and who interviewed him in Afghanistan, were satisfied that there was no evidence of any tie to terrorism.

Nevertheless, the USA told German officials that he could not be released unless Germany provided assurances of measures that amounted to "round the clock surveillance".
