HMP Leyhill: Security Concerns After New Year’s Day Prison Absconders

4 January 2026 Crime

Breaking Security Incident at HMP Leyhill

HMP Leyhill, a Category D open prison in South Gloucestershire, has made headlines following a serious security breach on New Year’s Day 2026. Matthew Armstrong and Daniel Washbourne are understood to have left the prison, in South Gloucestershire, at some time between 5-8pm on Thursday 1 January. The incident has raised important questions about security protocols at open prisons and the balance between rehabilitation and public safety.

Details of the Absconding Incident

HMP Leyhill reported the absconders to police on Thursday evening and officers attended the location at about 9.45pm to begin carrying out enquiries. Armstrong was convicted in the late-2000s of a murder that occurred during a robbery in Warwickshire, whilst Washbourne has previous convictions for violence against a person offences and false imprisonment. A third man who is suspected of absconding at the same time was arrested by Avon and Somerset Police in Bristol shortly after. The public has been warned not to approach either man and to call 999 immediately if spotted.

Understanding HMP Leyhill’s Role

Officially known as HMP Leyhill, this Category D facility offers a progressive environment with greater freedom and community-focused rehabilitation. Leyhill Prison has an operational capacity of approximately 532 inmates, according to Ministry of Justice data. The prison has been working on rehabilitation initiatives, with 20 inmates securing community jobs via ROTL (Release on Temporary Licence) in March 2025, boosting resettlement outcomes. However, the facility has also faced challenges, including an 8% staff shortage noted in January 2025, impacting programme delivery.

Significance for Public Safety and Prison Reform

This incident highlights the ongoing debate surrounding open prison facilities and their security measures. Rapid Deployment Cells are being rolled out at sites including HMP Leyhill, with places expected to come online by summer 2026 as part of the government’s broader prison expansion programme. Whilst open prisons play a vital role in preparing offenders for reintegration into society, absconding incidents underscore the need for robust risk assessments and monitoring systems. The manhunt continues, with authorities urging anyone with information to contact police immediately, reinforcing the importance of community vigilance in maintaining public safety.
