Mental health professionals decided not to detain the Nottingham triple killer Valdo Calocane despite a violent incident in 2020, after they considered research that addressed the over-representation of young black men in custody, a public inquiry has been told.
Calocane, who has paranoid schizophrenia, fatally stabbed 19-year-old students Barnaby Webber and Grace O’Malley-Kumar, and 65-year-old Ian Coates, and severely injured three others on 13 June 2023.
