Luke Horner

Former Thames Valley Police constable Luke Horner, aged 24, was sentenced to six years and four months' imprisonment at Northampton Crown Court on 6 October 2024 for committing a child sex offence. The conviction stemmed from an incident on 11 June 2023 in Rushden, Northamptonshire, where Horner, who was based at Amersham police station, sexually assaulted a teenage girl while off-duty. He was found guilty of engaging in penetrative sex with a child aged 13-15, an act described by police as abhorrent and having no place in policing or society.

Thames Valley Police released a statement following a review by His Majesty's Inspectorate of Constabulary and Fire and Rescue Services (HMICFRS) into Horner's vetting processes. The review, prompted by the severity of the offence, concluded that the force could not have reasonably anticipated Horner's criminal behaviour. DCC Ben Snuggs stated: "Our thoughts remain with the young girl and her family who have been affected by Horner's criminal behaviour. Such behaviour has no place in policing or in society." The HMICFRS report highlighted that Horner's initial vetting clearance was consistent with national practices at the time and that the force's Counter Corruption investigation in February 2022, prior to the incident, was not found wanting.

In response to the case, Chief Constable Jason Hogg chaired an Accelerated Misconduct Hearing, determining it was in the public interest to add Horner to the police barred list, preventing him from future employment in policing. The force has since invested in its Central Vetting Unit, including additional staff and a refreshed training course, to enhance applicant research, increase vetting interviews, and improve decision-making records. DCC Snuggs added: "We will review each of the HMICFRS recommendations carefully to ensure that any further changes to our processes are made. We want to help build a police service the public trusts in and will continue to remove those who have no place in policing." This case occurs amid broader national scrutiny of police misconduct, including recent findings of gross misconduct against Metropolitan Police officers in unrelated stop-and-search operations.

The incident and subsequent conviction underscore ongoing efforts within Thames Valley Police to strengthen vetting and maintain public trust, with the HMICFRS review affirming that no procedural failures directly enabled the offence.
