Revealed: failures at NHS hospital that left Nottingham triple killer free

Failures by the NHS trust responsible for treating Nottingham knife killer Valdo Calocane have been laid bare by the health watchdog – but The Independent can also reveal the hospital was repeatedly warned about poor care and experienced a steep rise in patient deaths over the last decade.

An investigation into mental health services in Nottinghamshire found that deaths of vulnerable patients in the years leading up to Calocane’s release from their care more than doubled from 1,694 in 2014-15 to 4,149 in 2021-22.

Calocane, a paranoid schizophrenic, stabbed 19-year-old students Barnaby Webber and Grace O’Malley-Kumar as they returned from a night out in June last year, before going on to kill 65-year-old Ian Coates.
