In 2019, the Offender Database recorded that Alistair Chapman, 29, was jailed for three years for plotting to kidnap and sexually abuse a 14-year-old girl. On appearing at Maidstone Crown Court in 2019, the defendant, of Easton Street, Portland, Dorset, was sentenced after pleading guilty to four counts, including arranging the commission of a child sex offence. It was reported that Chapman intended to restrain the victim with cable ties and duct tape and hide her in a wardrobe at his flat.
The investigation established that Chapman was in reality communicating with a decoy from the paedophile hunting group Shadow Hunters UK. Kent Police reported that the month-long grooming process involved Chapman sending videos of himself in bondage and discussing plans to get the 14-year-old pregnant. The prosecution reported that Chapman drove from Dorset to Sandling railway station near Folkestone on 21 April 2018, specifically instructing the “schoolgirl” to bring her uniform for his “vile” and “warped” fantasy.
Judicial Findings and Investigative Detail
The court reported that Chapman had demonstrated a considerable degree of planning to bring his “fantasy kidnap” to fruition. Maidstone Crown Court heard that the chatlogs between Chapman and the decoy ran to 400 pages, detailing penetrative sex and extreme restraint. The investigation established that when police raided his home on the Isle of Portland, they discovered “sickening” evidence of his intent, including coils of black cord, cable ties, and rolls of duct tape.
Judge Stephen Thomas noted that while there was no real victim, the state of mind displayed by Chapman was “troubling” and his behavior was “extreme and inexcusable.” For his actions in Folkestone and Portland, Chapman was handed a three-year prison sentence. The judge noted that the defendant believed the scenario was real and was fully prepared to carry out the “shameful” detention of a child in a cupboard at his flat.

Monitoring and Public Protection
In 2026, Chapman is managed under Multi-Agency Public Protection Arrangements (MAPPA) by the police and the National Probation Service in Dorset. Due to the nature of his conduct in Folkestone, which involved the detailed planning of a “vile” abduction and the possession of “bondage equipment,” his management is subject to high-level scrutiny. Authorities state that his indefinite inclusion on the Sex Offenders Register and his SHPO are critical tools to monitor his internet use and prevent him from accessing further victims.
As a member of the Sex Offenders Register indefinitely, Chapman must comply with all notification requirements regarding his identity and residence. Authorities state that his history of “disgraceful” grooming and his willingness to travel across the country to carry out a kidnap in Kent necessitates permanent vigilance. Any future attempt to contact minors, possess unmonitored digital devices, or fail to provide his passwords to the Public Protection Unit will result in immediate arrest and a return to the prison system.
