The case of Valdo Calocane is one of the most significant recent UK cases exploring the intersection of violent crime and severe mental illness. In June 2023, Calocane killed three people and seriously injured three others during a series of attacks in Nottingham. The legal outcome—an indefinite hospital order rather than a prison sentence—sparked public debate and led to an independent homicide report and a statutory public inquiry.
The central questions surrounding the case involve Calocane’s mental health history, the decisions made by NHS trusts and police in the years before the attacks, and whether the tragedy could have been prevented. The public inquiry, which began substantive hearings in February 2026, is now examining these issues in depth.
Who Is Valdo Calocane? Biography and Background
Valdo Calocane was a young man with a documented history of serious mental illness. According to multiple reports, he was diagnosed with paranoid schizophrenia in 2020. He had repeated contact with mental health services and police before the attacks, with a reported period of nine months without contact before June 2023, as detailed by Yahoo News and ITV News.
Calocane’s background before the attacks remains less fully documented in public records. Information about his education, family life, and any prior legal issues has not been widely published. What is known is that he had been sectioned multiple times and was under the care of the Nottinghamshire Healthcare NHS Foundation Trust.
Reports consistently state that Calocane was diagnosed with paranoid schizophrenia in 2020, a condition that the court accepted had profoundly diminished his responsibility for the attacks.
What Did Valdo Calocane Do? The 2023 Nottingham Attacks
On 13 June 2023, Valdo Calocane carried out a series of attacks that left three people dead and three others seriously injured. The attacks unfolded over a short period in the early hours of the morning, beginning in a residential area of Nottingham and moving into the city centre.
Where and when did the attacks happen?
The night before the attacks, Calocane arrived in Nottingham by train from London and took a tram to Wilkinson Street. He then wandered the city for hours, according to a timeline published by ITV News. At around 4:00–4:04 am on 13 June, police were called to Ilkeston Road after two students were stabbed. Barnaby Webber and Grace O’Malley-Kumar were found dead at the scene, according to Sky News and Wikipedia.

The three people killed were Barnaby Webber, 19, and Grace O’Malley-Kumar, 19, both students at the University of Nottingham, and Ian Coates, 65, a school caretaker whose van was later stolen by Calocane. Three other people were seriously injured: Wayne Birkett, Sharon Miller, and Marcin Gawronski, as reported by BBC News and the Nottingham Independent Inquiry.
What Was the Sentence and Conviction for Valdo Calocane?
In January 2024, Calocane appeared at Nottingham Crown Court. Prosecutors accepted pleas of not guilty to murder and guilty to manslaughter on the grounds of diminished responsibility, linked to his serious mental illness. The court also accepted guilty pleas to three counts of attempted murder.
Why did Calocane receive a hospital order instead of a prison sentence?
The judge imposed an indefinite hospital order under the Mental Health Act, rather than a standard prison sentence. This means Calocane is detained in a high-security psychiatric hospital, not a prison. The duration of the order is indefinite, with release subject to review by mental health authorities and the Ministry of Justice.
The case has been widely described as one of the most significant recent UK cases involving the interaction of violent offending and severe mental illness, according to BBC News and BBC News.
Calocane was not found unfit to plead. He pleaded guilty to mansaughter by diminished responsibility, which the court accepted. The hospital order means he will be detained for life, but in a hospital setting rather than a prison.
What Did the Independent Homicide Report into Calocane’s Treatment Find?
An independent homicide report commissioned by NHS England found serious failings by the mental health team responsible for Calocane’s care. A critical mistake identified was a premature discharge from care, according to the report published in February 2025, as reported by NHS England.
Which hospitals were involved in Calocane’s treatment?
The exact hospitals involved in Calocane’s treatment have not been fully specified in available public reports. However, the care was managed by the Nottinghamshire Healthcare NHS Foundation Trust, which runs several hospitals in the region, including Highbury Hospital and Rampton Secure Hospital.
How many times was Calocane discharged from care?
ITV News reported that Calocane had been discharged from NHS mental health services five separate times in the two and a half years before the attacks. The Nottingham Inquiry is examining his mental health management from 2019 to 2023, alongside police risk assessment and CPS charging decisions, as noted by Inquiry Tracker UK.
Why Was Valdo Calocane Not Detaained? The Mental Health Context
The question of why Calocane was not detained before the attacks is central to the public inquiry. The independent homicide report found that a premature discharge from care was a critical mistake. The report identified serious failures by the mental health team of the Nottinghamshire Healthcare NHS Foundation Trust.
Paranoid schizophrenia is a severe mental illness characterised by delusions and hallucinations, often leading to poor insight into the condition and difficulty with treatment adherence. Experts have pointed to the profound challenge of treating severe schizophrenia, where a lack of insight can lead to increased risk, according to the Health Services Safety Investigations Body (HSSIB).

The case has reignited debate on whether the Mental Health Act 1983 provides adequate safeguards for the public, particularly in assessing patient safety in the community.
What Happens Next? Public Inquiry and Implications for the NHS
A statutory public inquiry into the Nottingham attacks is underway. The inquiry’s substantive hearings began in February 2026, with a final report expected later. The inquiry is examining health services, police handling, and how risk was managed before the killings.
Recent reporting indicates the inquiry has been examining whether the attacks could have been prevented and whether earlier intervention might have changed the outcome. The families of Barnaby Webber and Grace O’Malley-Kumar have publicly expressed that they feel let down by the Crown Prosecution Service and the mental health system.
The government will be required to respond to the inquiry’s recommendations, which could lead to policy changes in mental health care provision or forensic psychiatry. The case will likely remain a benchmark for future discussions on mental health, public safety, and the criminal justice system.
