Alan Greaves, pictured, claimed 'the Illuminati framed him by downloading child abuse images on his computer . A father-of-eight caught with almost 20,000 images of child abuse on his computer and mobile claimed he was framed by the Illuminati. Police raided Alan Greaves's home in Colne, Lancashire in September 2013 where they found the disturbing images on a digital storage device. Forensic examination of the abuse images found almost 700 were of the most serious category, with a further 872 at the next level. Burnley Crown Court heard there were also 17,821 other indecent images with 106 movies. Laura Barbour, defending, said she had been instructed the reason Greaves had the images on his computer was because he was conducting an investigation on the 'Illuminati'. He believed the group 'disseminates' such material and that is how images ended up on his computer, the court heard. She added: 'He told police he has no interest in children sexually in any way.' The court was told the defendant, who has children aged around 30 to two-years-old, was also a full-time carer for his disabled sister. Jailing him for 21 months, Judge Simon Newell said there appeared to be sexually-explicit images of females aged just 10, or younger, which had assembled over a three-year period. 'If it was not for people viewing these images, there would be a chance these children would not be harmed,' he said. Greaves, who pleaded guilty to two offences of making indecent images, was also given a sexual harm prevention order and told to sign the sex offenders' register for the next 10 years. He is also barred from working with children. Burnley Crown Court, pictured, heard that almost 700 of the images were in the most serious category . The Illuminati featured in the movie Angels & Demons based on the best-selling novel by Dan Brown . Some conspiracy theorists claim the pyramid and eye on a US $1 note is evidence of the Illuminati . The Illuminati are a secret society who was founded in the late 1700s in Munich, Bavaria, named after the Latin word for 'Enlightenment'. The secret society has been blamed for a range of events by crazed conspiracy theorists. Some theorists have linked the organisation with the Battle of Waterloo; the French Revolution; the assassination of Presidents Lincoln and Kennedy. Others believe that the Illuminati control Hollywood and have a membership which includes senior political leaders. According to one conspiracy theory site, there are only 6,000 members worldwide with a ruling council consisting of five Americans, five western Europeans, one Russian and one Indian. The Illuminati claim they want to overthrow current governments and introduce their own New World Order. The organisation have been accused of being devil worshipers and conspiracy theorists claim that the Illuminati manifest their power by showing their symbols such as triangles, pyramids and the number 666. Conspiracy theorists believe the Illuminati want to rule the world with a single government which they control and introduce a single currency. The more far-fetched theorists claim the Illuminati control groups such as the Bildeberg group as well as the United Nations. They are also accused of having control of the Free Masons and other secret organisations.
