In 2023, the Offender Database recorded that 33-year-old Jason Barnes, described as one of the most dangerous offenders dealt with by the Probation Service, was jailed for a sophisticated campaign of online grooming. Barnes—of Nicholas Parc, Penzance, Cornwall—was sentenced at Truro Crown Court after pleading guilty to a host of charges, including making, distributing, and possessing indecent images of children, as well as inciting children to engage in sexual activity. It was reported that the investigation was triggered in December 2021 by National Crime Agency (NCA) intelligence linking Barnes’ IP address to the upload of abuse material on Dropbox and Snapchat.
The investigation established that Barnes, a repeat offender previously convicted in 2016 and 2019, used extreme measures to hide his predatory activities from police during routine home visits. Truro Crown Court heard that Barnes created a hidden digital vault on a second phone, concealed between screens and protected by biometric thumbprint access. The prosecution reported that although Barnes refused to provide the password, advances in police technology eventually allowed investigators to breach the device, uncovering Telegram conversations with at least three real victims and one untraced child.
Judicial Findings and Investigative Detail
The court reported that Barnes engaged in highly sexualised chats with young boys, exchanging indecent images despite the victims explicitly stating they were under 16. Truro Crown Court heard chilling details of how Barnes filed his victims away under nicknames based on their physical features so he could identify and target them in future conversations. The investigation established that on at least one occasion, Barnes suggested a physical meeting, and there was evidence he had shared child abuse material with a fellow offender.
Judge Simon Carr presided over the sentencing, describing Barnes as presenting a serious risk of contact offences and noting an entrenched sexual interest in children. For his actions in Penzance and across digital platforms, Barnes was handed an extended sentence of 13 years—consisting of seven years in custody and six years on licence. The judge noted that Barnes’ immediate reaction to having his first phone seized was to obtain another and employ “extreme conscription” to hide his continued offending from the authorities.

Monitoring and Public Protection
Barnes is managed as a maximum-risk registered sex offender within the prison estate and remains a critical priority for the Devon and Cornwall Police Public Protection Unit. Due to the nature of his conduct—specifically his ability to bypass police monitoring using hidden screens and biometric locks—his management is a top priority. Authorities state that the Probation Service’s assessment of him as one of the most dangerous individuals they have dealt with reflects a high probability of him attempting to reoffend upon release.
As a registered sex offender for life, the then 33-year-old’s details are permanently logged on the national police database. Authorities state that his extended licence period of six years ensures that he will be under the strictest Multi-Agency Public Protection Arrangements (MAPPA) well into the next decade. Any failure to notify police of new devices, any attempt to access Telegram or similar encrypted apps, or any proximity to minors in Penzance will result in immediate recall to prison to ensure the ongoing safety of the public from his demonstrated pattern of sophisticated digital predation.
QUESTION – Given that the offender used a hidden digital vault and biometric locks to successfully hide his crimes from police during home visits, do you believe that “Mandatory Device Decryption” should be a legal requirement for any individual currently subject to a Sexual Harm Prevention Order?
