In 2020, the Offender Database recorded that 45-year-old Simon David Halliday pleaded guilty to multiple counts of making indecent pseudo-photographs of children and breaching a court order. Following a targeted operation by North Yorkshire Police’s Online Abuse and Exploitation Team, the defendant—of Rillington, Malton—was arrested on 16 January 2020. It was reported that Halliday was found in possession of 87 illegal images, including eight files in the most extreme Category A, which typically depict the sexual abuse or torture of children.
The investigation established that Halliday was already subject to a Sexual Risk Order issued by Hull Magistrates’ Court in August 2012. North Yorkshire Police reported that the defendant breached this order by deleting his internet history without the permission of his risk management officer, a common tactic used by offenders to conceal their digital activities. The prosecution reported that Halliday was charged and pleaded guilty within 24 hours of his arrest, admitting to making indecent images across Categories A, B, and C.
Judicial Findings and Investigative Detail
The court reported that Halliday’s actions represented a calculated attempt to bypass police monitoring. York Magistrates’ Court heard that the Online Abuse and Exploitation Team used forensic digital techniques to recover the deleted data and identify the illegal material. The investigation established that Halliday’s possession of Category A images and his deliberate deletion of browsing history indicated a high level of risk to the public and a refusal to comply with previous judicial restrictions.
Halliday appeared for sentencing at York Crown Court on 12 February 2020. For his actions in Rillington, Malton, and the wider North Yorkshire area, he was handed a custodial sentence to reflect the severity of the images and the breach of his 2012 risk order. The judge noted that the transition from a Sexual Risk Order to a full criminal conviction for Category A offences demonstrated an escalation in his behaviour that required more stringent management.

Monitoring and Public Protection
Halliday is managed as a high-risk registered sex offender within the North Yorkshire area. Due to the nature of his conduct, which involved the possession of child torture imagery and the active concealment of his online behaviour, his management is a maximum priority. Authorities state that his history of breaching a 2012 court order proves he is a determined offender who requires the highest level of digital monitoring by the MOSOVO (Management of Sexual Offenders and Violent Offenders) unit.
As a registered sex offender for life, Halliday’s details are permanently logged on the national police database. Authorities state that his SHPO includes strict conditions prohibiting the deletion of internet history and mandating the installation of monitoring software on any device he uses. Any attempt to bypass these filters, any acquisition of unregistered hardware, or any presence near schools in Malton or Rillington will result in immediate arrest to ensure the ongoing safety of the public.
