Nottingham attacks: Why so many missed chances to stop Valdo Calocane?

The man who killed three people, and injured three others, has been sentenced to detention in a high-security hospital – with the judge saying he'll probably remain there for the rest of his life. Valdo Calocane fatally stabbed 19-year-olds Barnaby Webber and Grace O'Malley-Kumar and school caretaker Ian Coates in Nottingham in June last year. Speaking outside court, relatives of the victims criticised police, prosecutors and the NHS – saying they felt "let down" as Calocane’s mental health issues were widely known. On the Sky News Daily, Niall Paterson looks at what more could have been done to prevent the killings as he's joined by our communities correspondent Becky Johnson and Lisa Townsend, who is Conservative Police and Crime Commissioner for Surrey and mental health lead for the Association of Police and Crime Commissioners.Since recording this episode, Nottinghamshire Healthcare NHS Foundation Trust said the organisation had "robustly" reviewed its care of Calocane between May 2020 and September 2020. It added that it will continue to work with the police and health services to learn lessons.
