Prison Officer Falsified Cell Checks Before Inmate's Death in Mental Health Crisis
A devastating report from the Prison & Probation Ombudsman has uncovered a shocking cover-up at HMP Lincoln, where a prison officer lied about conducting vital cell checks on a vulnerable inmate who later died. Luke Ashcroft, a prisoner with severe mental health conditions, was supposed to be checked five times per hour while on suicide watch, but records were systematically falsified.
Systematic Failure in Care and Monitoring
Luke Ashcroft, imprisoned in 2018 for burglaries in Hull, suffered from schizophrenia and bipolar disorder. During his time at HMP Lincoln, he experienced acute psychotic episodes, telling healthcare workers about hallucinations of spiders in his body and expressing suicidal thoughts. Despite being placed on enhanced monitoring procedures, the system designed to protect him failed catastrophically.
The investigation revealed that on June 24, 2020, Ashcroft was not observed at all for the 18 minutes before he was found unconscious in his cell. He was discovered by a second officer who described the cell as "trashed" and was confused because falsified records indicated Ashcroft had been "fine only minutes earlier." The inmate passed away in hospital a week later.
Falsified Records and Missed Warning Signs
CCTV evidence conclusively proved that the night shift prison officer had failed to perform the majority of checks he had recorded in official logs. This officer was subsequently found guilty of misconduct in a public office for his deliberate deception.
The Ombudsman's report expressed particular concern about whether Ashcroft should have been placed in segregation at all. A nurse had ambiguously circled both 'Yes' and 'No' when asked if the prisoner showed signs of being acutely unwell on the segregation screening form, yet he was still placed in isolation.
On June 23, the day before his collapse, Ashcroft had exhibited severe symptoms, including spitting out water because he believed spiders' webs had contaminated it. A consultant psychiatrist documented that Ashcroft was "vividly hallucinating" and experiencing an acute psychotic episode with delusional parasitosis, recommending transfer to a secure psychiatric hospital.
Inquest Findings and Institutional Response
A jury inquest conducted from March 2 to 17, 2026 concluded that Ashcroft had not intended to end his life and died by misadventure. The Ombudsman's report highlighted multiple systemic failures beyond the falsified records, including inadequate assessment of whether Ashcroft was medically fit for segregation.
The Prison Service has acknowledged the findings, with a spokesperson stating: "Our thoughts remain with the family and friends of Luke Ashcroft and HMP Lincoln has accepted the Prison and Probation Ombudsman's recommendations. We have already made changes to better support prisoners at risk of self-harm or suicide, including improving training for all staff and introducing additional assurance checks."
Recommendations for Systemic Reform
The Ombudsman has made specific recommendations to both the Governor and Head of Healthcare at HMP Lincoln to scrutinize the Initial Segregation Health Screen more rigorously when forms appear incomplete or contradictory. While a clinical reviewer concluded that Ashcroft received healthcare comparable to community standards, the monitoring failures proved fatal.
This case exposes critical vulnerabilities in prison mental health protocols and monitoring systems, raising urgent questions about accountability and reform in the treatment of inmates with severe psychiatric conditions.
