A jihadi who hid extremist instruction manuals in James Bond-style cufflinks has been jailed for eight years.

Samata Ullah has been described by police as a "very dangerous individual" after he created online instructions on how to build explosives and avoid detection by the authorities.

The 34-year-old from Cardiff downloaded those instructions, along with extremist material, onto USB sticks disguised as cufflinks.

When police raided his home in October last year, they found 60 cufflink USB sticks around his bedroom.

Ullah admitted five terror offences, including membership of the Islamic State terror group, as well being involved in terrorist training and preparation for terrorist acts.


He was given an extended sentence of eight years in jail with a further five years on extended licence.

Commander Dean Haydon, head of Scotland Yard's counter-terror unit, said: "Ullah was a very dangerous individual. He operated primarily on the internet. I would class him as an internet terrorist.

"He provided a one-stop-shop for terrorists around the world to access. He provided a library of propaganda material, relating primarily to Daesh (Islamic State).

"He provided instruction and guidance in relation to accessing weapons and weapons systems and as a result, we know terrorists around different parts of the world did actually access this material and found his website extremely useful."

From utopia to jihad - IS' changing propaganda

Ullah was a key member of a group calling itself the 'Cyber Caliphate Army' and gave other members of IS advice on how to communicate using the kind of sophisticated encryption techniques employed by online hackers.

The court heard he used voice modulation software to disguise his Welsh accent in the videos and wore woolly gloves to disguise his skin tone.

In all, officers seized 150 devices and trawled through eight terabytes of data - the equivalent of 2.2m copies of the ebook of War And Peace.

Ullah, a divorced British national of Bangladeshi origin, had recently resigned from his job as an insurance worker and came to the attention of police following the arrest of a terror suspect in Kenya.

A search of that man's property found he had downloaded Ullah's instruction manuals.

Scotland Yard say a number extremists linked to IS have already downloaded Ullah's internet files. Some have been arrested but many others may well have viewed the terror instructions he sent out.

Although Ullah, described as a loner, was recently diagnosed with autism, authorities say he is still a very dangerous individual.
