Samata Ullah , a Welsh based jihadi, who hid extremist instruction manuals in James Bond-style cufflinks, has been jailed for 8 years.
He 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 membership of the Islamic State terror group, as well being involved in terrorist training and preparation for terrorist acts.
The head of Scotland Yard’s Counter Terror unit, Commander Dean Haydon told Sky News: “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).
