Summer 2001: Candidate 9/11 Hijacker Possibly Arrested in US, Then Released

A candidate 9/11 hijacker named Abderraouf Jdey is possibly arrested and then released in the US around this time, although details remain very murky.
CIA Officer’s Curious Report – In 2010, Rolf Mowatt-Larssen will write a public report for the Harvard Kennedy School entitled, “Al Qaeda Weapons of Mass Destruction Threat: Hype or Reality?” Mowatt-Larssen was a CIA official from 1982 to 2005, and was head of the CIA’s Counterterrorism Center (CTC) for a time. Around the time of 9/11, he was the head of the CTC’s weapons of mass destruction branch (see 1982, Early October-December 2001, and November 2005). In a timeline in Mowatt-Larssen’s report, there is this entry for Summer 2001: “Detention of Abderraouf Yousef Jdey, a biology major with possible interest in biological and nuclear weapons, who traveled with Zacharias Moussaoui from Canada into the United States. Moussaoui is detained with crop duster manuals in his possession; Jdey had biology textbooks. Earlier, they attended McMaster University in Canada, along with Adnan Shukrijumah.” This entry is very curious, because although the report is said to be based entirely on publicly sourced material, there has been no public information about Jdey’s arrest or link with Moussaoui, and the footnotes to the entry do not mention these things either.

Jdey’s 9/11 Connection – In late 1999, Jdey may have attended an advanced training course in Afghanistan also attended by 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi (see Late 1999). He may also have been instructed by 9/11 mastermind Khalid Shaikh Mohammed at the same time as hijacker Mohamed Atta and Ramzi bin-al-Shibh. A letter recovered from a safe house in Afghanistan in late 2001, apparently written by al-Qaeda leader Saif al-Adel, says that Jdey was originally meant to be one of the 9/11 hijackers. A videotape of Jdey pledging to be a martyr was also discovered in mid-November 2001 in Afghanistan, in the wreckage of al-Qaeda leader Mohammed Atef’s house (see November 15-Late December 2001).

Jdey Is Highly Wanted After 9/11 – Jdey was born in Tunisia, but became a Canadian citizen in the mid-1990s. After 9/11, it is known that he leaves Canada in November 2001. In January 2002, the US government will announce they are seeking him. In 2005, the FBI will announce a $5 million reward for him.

Mystery Is Unresolved – If Mowatt-Larssen is correct and Jdey was arrested before 9/11, this would have been a vital opportunity to stop the 9/11 plot, and if he was connected with Moussaoui, that would dramatically change the circumstances of Moussaoui’s arrest. It would also mean there would had to have been a cover-up of Jdey’s arrest in the years since 9/11.
