Pensioner with 'largest hoard' of child abuse images found in Scotland jailed

An 83-year-old pensioner from Stenhousemuir, Alan MacPherson, has been sentenced to four years in prison after police uncovered what is believed to be the largest collection of child sexual abuse material ever seized in Scotland. Following a police raid on his home in 2025, authorities discovered over two million images stored across multiple electronic devices. Of these, more than 805,000 were confirmed to depict child sexual abuse, with a significant portion classified in the most severe category. The sheer volume of the collection meant that much of the material remained unexamined and uncategorized.

During sentencing, Sheriff Mayram Labaki described the scale of MacPherson’s offending as “exceptional.” She emphasized the gravity of the crime, noting, “The quantity [of images] was so great that a substantial proportion could not be examined and categorised by forensic examiners.” The sheriff further remarked, “Every image records the abuse or exploitation of a child. The possession and circulation of such material perpetuates that abuse.” In addition to his prison term, MacPherson will be subject to three years of supervision after release and will be placed on the sex offenders register for life.

The court heard that police seized nine electronic devices from MacPherson’s residence, including computers, phones, digital cameras, USB sticks, and external drives, all containing illicit material. Five of these devices underwent comprehensive forensic examination. At least one device alone had nearly 1.4 million ungraded images due to the enormity of the collection. Authorities tracked MacPherson down after detecting his IP address being used to distribute child abuse material. Prosecutor Rachel Wallace revealed that in July 2025, MacPherson shared several highly serious images during an online exchange with an undercover officer. Although he used a messaging app intended to guarantee anonymity, police were able to trace the activity back to his home. The victims, mainly girls aged between nine and 15, included at least one who may have been as young as seven. Wallace stated, “Police have advised us this is quite possibly the largest collection of child sexual abuse material ever seen by Police Scotland.”

At his arrest and subsequent interview, MacPherson admitted to searching for indecent images of children online over a 14-year period “for his own personal gratification.” Sheriff Labaki criticized his lack of remorse, citing comments in the social work report where MacPherson claimed the children were consenting and willing participants. The sheriff condemned this attitude as “unconscionable.”

Representing MacPherson, solicitor advocate Stephen Biggam mentioned that his client is experiencing progressive vision loss due to macular degeneration, which might reduce any future risk. Biggam also disclosed that MacPherson’s wife had served him divorce papers during custody and that he was largely estranged from his family and society. The Royal Scottish Country Dance Society, where MacPherson had served as an honorary archivist in a voluntary capacity, expressed their horror at the offenses. A spokesperson stated, “We are shocked and appalled by the offences committed by Alan MacPherson and the details which have emerged through these court proceedings.” They reaffirmed their commitment to safeguarding and urged anyone with concerns about MacPherson’s association with the society to come forward, ensuring that all reports will be handled seriously and passed to the relevant authorities if necessary
