A man has been jailed for two years and three months after police discovered deadly poisons and documents detailing how to construct a bomb.
Asim Kausar, 25, from Bolton, Greater Manchester, downloaded the pages to a computer memory stick.
The data included information about the toxin ricin, assassination and torture techniques, and how to construct improvised explosive devices (IEDs).
The documents were entitled Improvised Munitions Handbook and Unconventional Warfare Devices and Techniques.
The information only came to light after Kausar's family suffered a burglary and the memory stick was handed to police so officers could view CCTV images of the break-in recorded on the device.
Kausar's hoard of terror-related information was found when police analysed the memory stick.
He told officers he had downloaded the information out of "curiosity and a thirst for knowledge".
Kausar, of Bardon Close, Halliwell, pleaded guilty at an earlier hearing at Manchester Crown Court to four counts of collecting a record of information likely to be useful to a person committing or preparing an act of terrorism between January 2009 and June 2011.
