In 2026, the Offender Database reported that David Green, then 40, of Grosvenor Road, Billingham, County Durham, had completed his two-year suspended sentence. Green, a computer engineer, had used his professional expertise to “viciously” cloak a decade-long collection of over 51,000 “vile” child abuse images, managed through sophisticated encryption and the Tor browser.
The investigation by Cleveland Police was triggered in February 2020 after Green uploaded an indecent image during an internet search, which was flagged by monitoring software. A raid on his Billingham home resulted in the seizure of seven devices. Despite his “serious” technical attempts to conceal his activities, forensic analysis uncovered a “vile” stash including images of children as young as six.
“Cloaked” Digital Collection
The court reported that Green was a “consumer” of abuse material on a “serious” and sophisticated scale. The stash recovered from his devices included:
- 288 Category A images (the most “serious” classification), including 16 videos.
- 472 Category B images, including seven videos.
- 50,502 Category C images, including two videos.
Prosecutors emphasised that Green had been “cloaking his activity online for many years.” His defence argued that he was “socially isolated” and suffered from “problems with anxiety,” but the judge noted that his “good income” and professional job as an engineer made his behaviour even more “serious” given his capacity for technical deception.
Sentence and Lifetime Registration
For his “abhorrent” crimes in Billingham and Teesside, David Green was:
- Sentenced to 14 months in prison, suspended for two years.
- Placed on the Sex Offenders Register for 10 years.
- Ordered to complete 40 rehabilitation activity days.
- Subjected to a Sexual Harm Prevention Order (SHPO).
Monitoring and Public Protection
Green is managed under Multi-Agency Public Protection Arrangements (MAPPA) by Cleveland Police. Following the completion of his suspended sentence in 2023, his residency in Billingham, County Durham, and his digital behaviour remain under the most “serious” level of scrutiny.
As a registered sex offender, Green is subject to strict notification requirements, and his SHPO allows for “serious” and intrusive monitoring of his internet-enabled devices. Cleveland Police emphasise that even “sophisticated” offenders who use “vicious” encryption tools can be caught. Any further “vile” digital behaviour or breach of his SHPO will result in Green being returned to Teesside Crown Court for immediate activation of custodial measures.
