A teenage extremist who tried to radicalise his younger brothers is facing jail after he was exposed by a Dutch blogger for posting radical material online.
Sudesh Mamoor Faraz Amman, 18, from Harrow, North London, used a family Whatsapp group to share recruitment material with his five younger brothers.
The document, an al-Qaeda magazine called Inspire, edition 16, was sent to the group, which also included extended family members in Sri Lanka.
It encouraged readers to launch lone wolf attacks following pipe bomb attacks in New York and New Jersey in September 2016.
He also shared bomb-making instructions with a person he was in a relationship with, according to prosecutors.
Amman smiled and laughed throughout the hearing at the Old Bailey, including when he was told by Judge Mark Lucraft QC, that he was facing a custodial sentence of 'some length.'
He pleaded guilty to six counts of possessing material useful for terrorism and seven counts of disseminating material on Skype between April 19 2017 and April 2 2018, on the basis of recklessness.
Kathryn Selby told an earlier hearing that Amman came to the attention of police through a Dutch blogger who captured postings of an 'extremist Islamic nature.'
He was arrested by armed police in a street in North London after Mark Van Der Berg, who runs an anti-extremist blog, highlighted the existence of posts in a closed Telegram chat room.
Amman's social media chat was said to have included an 'expressed desire to carry out a knife attack.'
When police arrested him they found he had instructional material on knife fighting techniques, including documents called Bloody Brazilian Knife Fighting Techniques, US Army Knife Fighting Manual Techniques and Close Combat.
He also had a number of bomb-making manuals including How to make a bomb in the Kitchen of your Mom, the Improvised Munition Handbook, and the Anarchist Cookbook.
Bearded, with long hair, glasses and a black prayer cap, Amman was living at home with his mother and six other siblings who are said to be known to social services.
The material he disseminated, which began when he was 17, included the document How to make a bomb in the Kitchen of your Mom and a number of gory videos with titles including The Islamic State - my revenge, and Let's go for Jihad.
He denied that the Army of Madinah in Kashmir, a book by the British al-Qaeda leader Dhiren Barot - who is serving 30 years for a plot to blow up central London hotels using radiological 'dirty bomb' - was a terrorist publication.
Two charges related to possessing and disseminating the book on Whatsapp and Skype, were ordered to lie on file, along with a charge of possessing a document on making plastic explosives from bleach.
Amman will be sentenced next month.
