Adam David Bonner
Introduction
Adam David Bonner, a 19-year-old former soldier from Middlesbrough, was sentenced to three years and four months in a Young Offender Institution for a catalogue of child sexual abuse offences committed while he was serving in the British Army — including making and distributing indecent images of children and attempting to cause a girl under 13 to engage in sexual activity . Bonner pleaded guilty to eleven offences in July 2026 and was sentenced at York Crown Court on 11 November 2026 . His offending was traced by an online child abuse policing unit to army barracks across England and Scotland — and he will be subject to public protection measures, in the detective’s words, “for the rest of his life” .
Background Information
Bonner came to the attention of North Yorkshire Police’s Online Child Abuse Team (OCAT) in March 2025, when a computer suspected of being used to download hundreds of indecent images of children was traced to his previous army barracks in Devon . After enquiries established his identity, he was arrested at Catterick Garrison — the army base where he was then stationed — on 16 April 2025 . Detectives and digital forensic specialists went on to prove a catalogue of offending spanning the locations where Bonner had been stationed during his army service, including Dorset, in Scotland, and his hometown of Middlesbrough .
The Controversy or Incident That Led to Their Cancellation
Convicted and sentenced: three years and four months for eleven child sexual abuse offences admitted in full.
The eleven offences Bonner admitted in July 2026 included making and distributing indecent images of children in categories A, B and C — the most severe classification — engaging and attempting to engage in sexual communication with a child, possessing a prohibited image of a child, attempting to cause a girl aged under 13 to engage in sexual activity, attempting to cause a child under 13 to look at an image of sexual activity, and possessing an extreme pornographic image involving an animal . Detectives seized numerous digital devices from Bonner’s army quarters, all linking back to him, and established from the point of arrest that he held a large volume of child sexual abuse material along with the extreme images . Sentencing followed at York Crown Court on 11 November 2026, where the court imposed the custodial term alongside indefinite-range protective orders .
Public Reaction and Consequences
Detective Sergeant Graeme Bevington of the Online Child Abuse Team said Bonner’s offending was “truly reprehensible” and welcomed that he was “now behind bars for a significant period of time” . He emphasised that Bonner would be subject to “robust public protection measures for the rest of his life” — a reference to the sentence’s layered conditions, which include sex-offender registration, a bar on working with children or vulnerable adults, and a 10-year Sexual Harm Prevention Order . The case was reported locally on Teesside as a disgraced-soldier story, with the image of a teenage recruit arrested inside his own barracks becoming its defining frame .
Current Status
Bonner is serving his three-years-and-four-month sentence in a Young Offender Institution, placed on the Register of Sex Offenders, barred from working with children or vulnerable adults, and bound by the 10-year Sexual Harm Prevention Order imposed at sentencing . His army career is over; police described him as a “now former soldier” in announcing the outcome . No appeal was reported in the coverage of the sentencing .
Impact on Their Career/Life
Bonner’s military career — begun in Devon, continued at Catterick Garrison — ended with his arrest inside the base in April 2025 and now sits behind a conviction record of eleven child sexual abuse offences admitted in full . The lifetime registration and children-barred list mean the consequences will outlast both his sentence and his youth, and the force’s public protection message framed the conditions as the case’s real legacy . For investigators, the case demonstrated the reach of online child abuse teams into military as well as civilian settings — from a Devon barracks computer to a courtroom in York within nineteen months .
