A 34-year-old man has admitted possession of terrorist documents containing details of how to make explosives, poisons and mines.
Umer Farooq, from Stockport, appeared at the Old Bailey by videolink today and admitted 14 counts of possession of material that could be useful to a terrorist.
This included copies of al Qaida magazine Inspire, the Terrorist Handbook Of Explosives, and other documents about "homemade C4", guns with silencers, "home built mines" and "silent killing".
One computer file contained information about the collection of evidence at crime scenes, while another bore the title "Black medicine: the dark art of death".
Farooq, who is in Belmarsh prison, was remanded in custody until November 16 when he will be sentenced at the same court.
