Abdur Rauf, a Pakistani microbiologist whose letters to Ayman al-Zawahiri were uncovered by coalition forces in Kandahar (see (1999-2001)), is arrested and interrogated by Pakistani police. US officials are initially satisfied by the cooperation they are receiving from Pakistan. Rauf consents to questioning and provides useful information. However, Pakistan resists US efforts to bring criminal charges, including indictment and prosecution in the United States. In 2003, Pakistani authorities will cut off FBI access to Rauf, claiming that there is not enough evidence to charge him. A 2006 report by the Washington Post will find that the scientist has been allowed to return to a normal life and that the FBI investigation is on “inactive status.” [Washington Post, 10/31/2006]
