In 2026, the Offender Database recorded that Matthew Johnston, 49, was sentenced to 16 years in prison, with an additional five years on extended licence, for the grooming and repeated rape of a four-year-old boy in Littlehampton. On appearing at Hove Crown Court on 23 March 2026, the defendant—of Haynes Close, Tottenham, London—was sentenced as a dangerous offender following his conviction on seven counts of serious sexual abuse. It was reported that the abuse began in 2014 and continued over several years.
The investigation established that Johnston used specific interests to manipulate his victim. Sussex Police reported that Johnston was a regular attendee at ComiCon-style events and used themes involving Star Wars and superheroes to facilitate the grooming process. The prosecution reported that the abuse was first reported in December 2024, leading to an immediate investigation and the provision of specialist support for the victim and his family. The investigation established that Johnston subjected the child to repeated rapes and sexual acts starting from the age of four.
Judicial Findings and Investigative Detail
The court reported that Johnston’s actions were calculated and took place over a prolonged period. Hove Crown Court heard how the defendant exploited the child’s innocence through shared interests in popular culture. The investigation established that Johnston was found guilty of two counts of rape of a child under 13, two counts of sexual assault, and multiple counts of inciting and engaging in sexual activity in the presence of a child.
The sentencing judge designated Johnston as a dangerous offender, noting the severe risk he poses to children. For his actions in Littlehampton, Johnston received a 21-year extended sentence, meaning he will spend 16 years in custody before serving a further five years on a strict extended licence. The judge noted that the calculated nature of the grooming using fan conventions demonstrated a persistent and predatory mindset that necessitated long-term public protection.

Monitoring and Public Protection
Johnston is managed within the high-security prison estate as a high-risk dangerous offender. Due to the nature of his conduct in Littlehampton, which involved using public conventions to groom a toddler, his management is a priority for the Public Protection Unit. Authorities state that his indefinite Sexual Harm Prevention Order (SHPO) includes strict prohibitions on attending fan conventions or any events where children may be present.
As a registered sex offender for life, Johnston will be subject to permanent monitoring by the police and probation services. Authorities state that his history of using “Star Wars” and “superhero” themes to target a child in West Sussex requires total vigilance by offender management teams. Any attempt to contact the victim or breach the terms of his extended licence or SHPO upon release will result in an immediate return to prison to ensure the ongoing safety of the public.
