A man who translated extremist videos and documents and uploaded them to YouTube has been jailed.

Counter-terrorism officers also found magazines which detailed how to make homemade bombs and literature about training to become a jihadi after a raid on Mohammad Aftab Suleman’s home in Crumpsall, Manchester.

Information about security measures, including the sending and receiving of encrypted messages and methods to detect and foil spies, was also discovered.

Suleman, 25, of Peakdale Avenue, pleaded guilty to five counts of possessing documents containing information of a kind likely to be of use to a person preparing or committing an act of terrorism and two counts of distributing a terrorist publication. At The Old Bailey in London today, he was jailed for 33 months.

Police said that although no evidence was found to indicate Suleman was planning an attack, the information he translated and uploaded could have influenced and helped others. Officers who swooped on his home in December last year seized computer equipment and a pen drive found in the pocket of a jacket in his bedroom.

The pen drive was found to hold more than 430 documents containing extremist literature. Two further laptops were seized. One was found to hold software allowing access to the ‘dark web’.

It later emerged that Suleman was planning to fly to Pakistan and he was detained at Manchester Airport.

Det Chief Supt Tony Mole, head of the North West Counter Terrorism Unit, called Suleman a ‘staunch supporter of Islamic extremism’.

He said: “The materials downloaded contained extremely dangerous and disturbing information, which were not stumbled upon by chance, but were actively searched for.

“Suleman also translated a number of existing extremist videos into English and uploaded them onto YouTube, so others could view and understand their content.

“From the literature and videos found in Suleman’s possession, it is clear he is a staunch supporter of Islamic extremism and whilst there is no evidence whatsoever to suggest he engaged in any attack planning, he went out of his way to distribute extremist materials and make them accessible to others.”
