GREGORY LYDALL'S SHOCKING CHILD PORNOGRAPHY CASE IN GUERNSEY
| Red Rose Database
Guernsey Child Sexual Abuser
In November 2019, the tranquil island of Guernsey was shaken by the revelation of a disturbing criminal case involving Gregory Lydall, a psychiatrist who had been employed by the States of Guernsey. Lydall, aged 44 at the time, was sentenced to 30 months in prison after admitting to multiple counts of downloading and possessing indecent images of children. His arrest and subsequent conviction have cast a long shadow over the island’s healthcare community and raised serious concerns about the safety and trust of vulnerable patients.
Prior to his arrest, Gregory Lydall was a senior figure within Guernsey’s Health and Social Care services, specifically working as an Adult Mental Health Services Consultant. His role involved providing care and support to some of the most vulnerable individuals, including those who had themselves endured childhood abuse. The gravity of his crimes, however, starkly contrasted with his professional responsibilities and the trust placed in him by the community.
In the summer of 2019, Lydall appeared before the Royal Court, where he admitted to downloading hundreds of indecent images depicting children under the age of 16. The evidence presented revealed that he had also downloaded and stored thousands of ‘pseudo images’—computer-generated images that depict child sexual abuse. The total charges against him included the creation and possession of over 700 ‘live’ images, as well as 4,137 pseudo images. These ‘live’ images were categorized into different levels of severity, with 716 falling into the most serious category one, and others spread across categories two through five. Some of these images featured children as young as three years old, although reports indicated that Lydall reportedly preferred images of older girls.
The investigation was initiated after Guernsey Police detected suspicious activity involving access to a website known for hosting child sexual abuse images. On January 10 of that year, officers executed a search warrant at Lydall’s residence. Upon arrival, they found him answering the door and promptly arrested him. During the search, law enforcement officers seized 66 electronic devices, including a laptop located next to his bed, multiple external hard drives, SSDs, and USB drives. Notably, two devices were plugged into the laptop at the time of the search. Subsequent examinations revealed that five of these devices contained images, many of which were encrypted and password-protected. Despite Lydall providing police with access codes, authorities were unable to open all files, with three encrypted files remaining inaccessible.
Further investigation uncovered that the laptop was equipped with software designed to facilitate mass downloads of files, as well as a VPN service that masked the user’s IP address, indicating an intent to conceal online activity. Additionally, evidence showed that thousands of files had been deliberately deleted from storage devices, making their contents unidentifiable. Some of the images were as recent as Christmas Day 2018, highlighting the ongoing nature of his offending.
During the court proceedings, Mr. McMahon, presiding over the case, expressed concern about the impact of Lydall’s actions on his colleagues and patients. He stated, “While some of your former colleagues and patients have been supportive of you, many are not going to be. We do not yet know the impact on those patients that your offending coming to light will have. We do know that your offending could have an effect on how the psychiatric services are perceived going forwards.”
Given the severity of the crimes, the court deemed that immediate custody was the only appropriate course of action. Mr. McMahon emphasized that if Lydall had not been arrested, he might have continued his offending or failed to seek help. Consequently, Lydall was sentenced to serve 30 months in prison. Following his release, he will be subject to an extended sentence license for three years, during which he will be prohibited from accessing the internet and will be closely monitored by probation officers. Furthermore, he will be under a notification order for ten years, requiring regular reporting to probation authorities.
Born in South Africa, Lydall trained as a doctor there before moving to the United Kingdom in 2003, where he obtained British citizenship. In 2010, he relocated to Guernsey to begin his first consultancy role, a move that ultimately led to his employment within the island’s healthcare system. His case has left a lasting impact on the community, raising questions about safeguarding and the vetting processes for healthcare professionals entrusted with vulnerable populations.
