Hoax bomber 'researched real bombs just months after leaving prison' With it was a note written in Arabic which said: "There is no God but Allah and Mohammed in the messenger of Allah. God is great, God is Great God is great. It added: "Britain must be punished'" and was signed off "al Qaeda Organisation of Iraq." He was released in January 2011 but by April he was searching the internet for terrorism methods, Duncan Penny, prosecuting, said. He spent up to 450 hours on research, the court heard. He tried to get around a ban on using the internet, a condition of his parole, by accessing computers in local libraries in South Yorkshire. Mr Penny said: "He made notes concerning the production of improvised explosives and about other plans connected with acts of terrorism which he apparently intended. He used computers in public libraries to access the internet, to conduct research on search engines and to view video clips on YouTube which were concerned with the manufacture of explosives. Roddis had at least eight aliases and three were blocked when he was caught using false identities at Rotherham's Central library. Detectives who examined his computer logs at the Central Library and the Rawmarsh library in Rotherham found the words he had searched included 'TATP', 'terrorism,' 'detonator' and 'July bombings.' His mother Jacqueline Eginton told police her son had mentioned 'something about a hard hat and some detonators in his shed.' She added that she 'didn't take any notice because he is always making ridiculous remarks.' Officers searched a property where Roddis had been living in Maltby. In the shed they found railway detonators, and a white hard hat. A visibility jacket identical to the ones worn by railway workers was discovered in a cupboard in the home. Recovered from the house were CDs, balaclavas and gloves, cassettes, electric cable and large quantities of handwritten notes One of the documents was a 'step by step guide' on how to make TATP, including details of the processes used by the 7/7 bombers. There were also shopping lists for trips to Boots, Wickes and Halfords for items including thermometers, hydrogen peroxide and acetone peroxide - two of the ingredients of TATP. Roddis claimed the notes he had made were was just part of his instructions for his lawyers. He accepted in the past he had stolen railway detonators - but said he liked to set off small explosions 'for his amusement.' Roddis denies engaging in acts for the preparation of terrorism.
