A schizophrenic man who killed three people caused a woman to jump out of her window after he was released by mental health professionals who considered the “over-representation” of young black men in detention, an inquiry has heard.

Valdo Calocane, who had been diagnosed with paranoid schizophrenia, killed University of Nottingham students Barnaby Webber and Grace O’Malley-Kumar, both 19, and caretaker Ian Coates, 65, and attempted to kill three more people, in Nottingham in June 2023.

In her opening statement on Monday, Counsel to the Inquiry Rachel Langdale KC said that nearly three years earlier in May 2020, Calocane kicked at a woman’s door while he was experiencing psychosis, leading her to jump from the first floor window out of fear and damage her spine.

Mental health workers and doctors had been “leaning towards” sectioning Calocane who had been arrested on suspicion of criminal damage earlier that day, but “the team of professionals considered the research evidence that shows over-representation of young black males in detention”, the inquiry heard.
