A sex offender, who had over 100,000 indecent images on his computer, has been jailed for two years.
Robert Orton aged 45 of Middlecott Close, Boston was arrested in March 2013 after police searched his home.
Computer equipment and two mobile telephones were taken away to be examined by experts.
A total of 131,366 indecent images were found on the items seized. Most were of the least serious category but approaching 500 were assessed as belonging in the two most serious categories.
On Friday 28th February Orton pleaded guilty to 12 charges of making and possessing indecent images of children at Lincoln Crown Court. He also admitted two charges of breaching a sexual offences prevention order.
Detective Inspector Simon Lovett leads the Lincolnshire Police Internet Child abuse Team (ICAT) said: "The activity is abhorrent. Each picture effectively shows a crime scene. We are determined to protect and rescue children in such situations by all possible means."
