83-year-old man linked to Scotland's biggest child abuse image cache
An 83-year-old resident of Stenhousemuir was found with over two million child sexual abuse images, the largest haul ever seized by Police Scotland.
Falkirk Sheriff Court heard that Alan MacPherson, an 83-year-old from Stenhousemuir, possessed what is believed to be Scotland’s largest collection of child sexual abuse material, exceeding two million files. A 2025 raid uncovered nine devices - computers, phones, cameras, a USB stick and external drives - all holding indecent images, and five of these were fully examined. While 805,000 images were formally classified as abusive, roughly 1.4 million on one drive remained ungraded due to the sheer volume.
Prosecutor Rachel Wallace noted that MacPherson had posted Category A material to an anonymous messaging app while interacting with an undercover officer. He admitted to seeking the content for personal gratification and was sentenced to be placed on the Sex Offenders Register and remanded in custody pending pre-sentence reports. Defense solicitor Stephen Biggam highlighted MacPherson’s deafness and macular degeneration, and Sheriff Craig Harris warned the public gallery about the graphic nature of the evidence.
Why it matters
The case reveals the scale of online child exploitation and challenges law enforcement's capacity to process massive digital evidence.
