A man arrested by police investigating the July 7 bombings has pleaded guilty to possessing an al Qaida training manual.
Khalid Khaliq, 34, admitted owning the CD after it was found in a raid at his home on Tempest Road in Beeston, Leeds, in July 2005.
Judge James Stewart QC told Leeds Crown Court that Khaliq would face a maximum two-year sentence.
Khaliq is understood to feature on an infamous photograph which shows him white-water rafting in North Wales with London bombers Shehzad Tanweer and Mohammad Sidique Khan.
The unemployed single father-of-three was one of four people arrested in West Yorkshire and Birmingham by anti-terror police officers on May 9 last year.
The other three - Hasina Patel, the widow of July 7 ringleader Mohammad Sidique Khan, her brother Arshad Patel and Imran Motala - were released without charge a week later.
Khaliq was arrested at a house close to bomber Tanweer's family home in the Beeston area of Leeds.
An al Qaida training manual was discovered at Khaliq's home during a raid in 2005.
The charge of possessing a book called Zaad-e-Mujahid (Essential Provision of the Mujahid), which was found in a separate raid last year, was ordered to be laid on file. Judge Stewart ordered Khaliq to be found not guilty of a further charge of possessing the book The Absent Obligation.
Khaliq was bailed to be sentenced at Leeds Crown Court.
