When traveling with a radical associate known to be monitored by German intelligence, Abdulrahman al-Makhadi (see Late 1996 or After), Ziad Jarrah meets another suspicious Islamic radical. The man, a convert, is known in public accounts only as Marcel K and is the vice president of the Islamic center in North-Rhine Westphalia. In March 2001, the Bundeskriminalamt federal criminal service will begin investigating the center’s president with respect to membership in a terrorist organization. Marcel K is apparently a close confidant of Jarrah, because Jarrah always calls him before taking important decisions, for example when he leaves to train in Afghanistan and when he applies for admission to US flight schools. He will also call Marcel K during his pilot training, for the last time shortly before 9/11. [Frankfurter Allgemeine Zeitung (Frankfurt), 2/2/2003] Marcel K will be arrested in a Europe-wide sweep of Islamic militants in February 2003. [Deutsche Welle (Bonn), 2/6/2003; Tagesspeigel, 2/7/2003; New York Times News Service, 2/7/2003] It is not known what happens to him after this.
