The NHS trust that treated Nottingham attacks killer Valdo Calocane is being investigated for corporate manslaughter.
Calocane, who had been diagnosed with paranoid schizophrenia before he fatally attacked Barnaby Webber, Grace O’Malley-Kumar and Ian Coates in June 2023, was previously sectioned by Nottinghamshire Healthcare NHS Foundation Trust.
A public inquiry, which finished hearing evidence in May, was told he had been discharged in 2022 because he failed to turn up for appointments and the team had “lost” him.
The investigation into the trust is being carried out by Northumbria Police.
Nottinghamshire Police has been criticised over its history of interactions with Calocane and its handling of the response and investigation into the attacks.
A spokesperson for Nottinghamshire Healthcare NHS Foundation Trust said: “Northumbria Police, acting on behalf of Nottinghamshire Police, have begun an investigation into matters relating to the care and treatment of Valdo Calocane.
“We know how important the independent inquiry and police investigation are for the affected families, the survivors and our local communities.
“We will, of course, be co-operating fully with Northumbria Police, as we have with the Statutory Inquiry into these matters which is being chaired by Her Honour Deborah Taylor, and which will hear final submissions from all the parties involved later this year.”
