In 2003 , Al-Moayad traveled to Germany to meet a Federal Bureau of Investigation ( FBI ) informant , Mohamed Alanssi , and a FBI undercover agent posing as a wealthy former Black Panther . The FBI video-recorded al-Moayad at a Frankfurt hotel promising to funnel over $ 2 million to Hamas . He was then arrested by German police at the request of the FBI . Al-Moayad 's assistant Mohammed Mohsen Yahya Zayed was also arrested . They appealed to the Federal Constitutional Court of Germany against extradition . This appeal was rejected , as the court found that the U.S. had given Germany assurances that the suspects would not face a military court or any other special tribunal . They were therefore turned over to U.S. custody , and taken to New York City to face trial . It was decided to try them at the U.S. District Court in Brooklyn , because al-Moayad was alleged to have done some of his fundraising at a Brooklyn mosque . At the time of the arrests , John Ashcroft said that al-Moayad had admitted to funding Osama bin Laden with $ 20 million prior to the September 11 attacks
