James Castell

James Castell, a 40-year-old resident of Heathfield in East Sussex, became one of the first individuals in Sussex to be sentenced for producing AI-generated child sexual abuse material. The case emerged from an investigation by the Sussex Police Online Child Abuse Team (OCAT), which uncovered a disturbing collection of illegal content on his digital devices.

In October 2024, officers raided Castell's home on High Street, Heathfield, seizing multiple devices including computers and storage media. Forensic analysis revealed over 3,800 indecent images of children, with 640 classified as Category A—the most severe level—depicting penetrative acts, bestiality, and sadism. Among these, police identified AI-generated images created using specialised software that produced abusive visuals based on text prompts. Evidence showed Castell had distributed at least one such AI-created image online, and further investigation indicated a sexual interest in children as young as three years old.

Castell was arrested during the raid and later pleaded guilty to multiple child sex offences at Hastings Magistrates’ Court on 8 October 2024. His sentencing took place on 19 December 2024 at Lewes Crown Court, where Judge [name not specified in article] imposed an 18-month prison sentence, suspended for two years. In addition to the suspended term, Castell was subjected to a 10-year Sexual Harm Prevention Order, which severely restricts his internet access and prohibits contact with children. He was also placed on the Sex Offenders Register for 10 years, required to complete 240 hours of unpaid community work, and mandated to participate in rehabilitation programmes aimed at addressing his offending behaviour.

• Key evidence: Over 3,800 indecent images, including 640 Category A.
• AI involvement: Software used to generate images from text prompts.
• Distribution: At least one image shared online.

Detective Chief Inspector Luke Kyriakides-Yeldham of Sussex Police commented on the case, stating, “Every child sex abuse image created or shared fuels this despicable industry, and James Castell has shown absolutely no regard for children’s safety. AI is a new tool for criminals, but make no mistake, using it to create such images is a serious crime. We’re working hard to catch offenders and bring them to justice.” The investigation highlights the growing challenge of AI in facilitating child sexual exploitation, with Sussex Police emphasising their commitment to combating such emerging threats. The case was reported by UKNIP on 24 December 2025, drawing attention to the evolving nature of online child abuse investigations in the UK.
