The Nottinghamshire Healthcare NHS Foundation Trust is under criminal investigation for corporate manslaughter regarding its treatment of Valdo Calocane. Calocane, who suffers from paranoid schizophrenia, killed three people in Nottingham on June 13, 2023. Northumbria Police are conducting the inquiry on behalf of the Nottinghamshire force, which is also subject to scrutiny for its own handling of the case.
Care and Treatment History
A public inquiry into the 2023 attacks revealed that the trust had sectioned Calocane four times between 2020 and 2022. Evidence presented to the inquiry indicated that Calocane had a history of violent incidents and frequently refused medication. During his second hospital admission, a doctor reportedly warned that he could potentially kill someone. Despite these warnings, he was discharged from mental health services in September 2022 after failing to attend appointments and becoming unreachable by staff.
Ongoing Investigations and Accountability
The corporate manslaughter investigation could lead to significant fines and potential leadership changes at the trust. The trust has confirmed it is cooperating with Northumbria Police, as it has with the ongoing statutory inquiry. The inquiry, which is expected to publish its findings in 2027, also examined the failure of local police to execute an arrest warrant for Calocane that was active at the time of the attacks. A 2026 report by the Care Quality Commission previously stated that the trust required significant improvements.
