Nottingham Attack Inquiry Exposes Systemic Failures in Mental Health and Policing
6/8/2026, 9:57:30 PM
The Tragic Attack and Immediate Aftermath
On 13 June 2023, Valdo Calocane—diagnosed with paranoid schizophrenia in 2020—stabbed University of Nottingham students Barnaby Webber (19) and Grace O’Malley-Kumar (19) and caretaker Ian Coates (65) to death. He then stole Coates’s van and struck pedestrians Wayne Birkett, Sharon Miller and Marcin Gawronski, leaving them with life-changing injuries. Calocane pleaded guilty to three counts of manslaughter on the grounds of diminished responsibility and three counts of attempted murder and received an indefinite hospital order in January 2024.
Inquiry Findings: Systemic Breakdowns
A 14-week public inquiry, hearing from 164 witnesses, identified multiple failures. Mental-health services discharged Calocane in 2022 without a detailed handover, lost contact after he missed appointments, and failed to manage his known non-compliance with medication. Police did not execute a September 2022 arrest warrant despite nine months to act, and families received delayed, inconsistent information about the victims’ deaths. The inquiry also uncovered widespread inappropriate access to victims’ medical records by police, NHS, and court staff, prompting disciplinary action.
Official Responses from Government and Agencies
- A spokesperson for Prime Minister Sir Keir Starmer said the government is “determined to ensure that nothing like this can ever happen again” and is “committed to delivering the fundamental changes needed to prevent violence by those who are mentally unwell.”
- Nottinghamshire Police admitted a “serious and systemic and operational failure” for not arresting Calocane, announced daily reviews of warrant procedures, and faced five investigations by the Independent Office for Police Conduct.
- Nottingham University Hospitals NHS Trust dismissed 11 staff, issued final written warnings to 12 and first warnings to two for accessing victims’ records; medical director Manjeet Shehmar apologized for the “additional distress” caused.
- Dr Sinead O’Malley-Kumar, mother of Grace O’Malley-Kumar, stressed that “we can’t have these inquiries without meaningful change afterwards.”
Families and Survivors: Calls for Accountability
Emma Webber, mother of Barnaby, described a “catastrophic collapse of responsibility” and an “undoubted miscarriage of justice.” The bereaved families demanded an urgent re-examination, a meeting with the Attorney General within a month, and a public memorial. Survivors’ solicitor Greg Almond highlighted that the victims were “ordinary, hard-working people” and called for transparent accountability.
Data, Statistics, and Timeline
- Fatalities: 3; Injured: 3.
- Calocane was sectioned four times; discharged in 2022 after failing to attend appointments.
- Prior incidents: May 2020 psychotic episode; July 2021 house-mate assault; Jan 2022 headlock; May 2023 warehouse assault.
- Arrest warrant issued Sep 2022, not executed.
- Inquiry: 23 Feb 2024 – mid-2024, 14 weeks, 164 witnesses.
- NHS disciplinary actions: 11 dismissals, 14 written warnings.
- Police investigations launched: 5.
Conflicting Accounts and Gaps
Families claim the Crown Prosecution Service intended to accept not-guilty pleas on diminished responsibility, yet Calocane ultimately pleaded guilty to manslaughter. Police gave Barnaby’s parents notice of death after 10:00 am, while Ian Coates’s partner was first told he had died in a road accident. The full extent of staff who accessed victims’ records remains under audit.
Why the Findings Matter
The inquiry highlights the need for integrated mental-health and public-safety protocols, reforms to police warrant execution, stricter data-protection safeguards, and equitable resource allocation to cities outside London. Unaddressed, these systemic gaps could jeopardise future responses to individuals with severe mental illness.
