Valdo Calocane approached security at Thames House in 2021 but did not meet threshold for further assessment, public inquiry told
A man who killed three people during a 2023 knife attack in Nottingham had attempted to hand himself into MI5 for arrest two years earlier, an inquiry has heard.
Valdo Calocane, 34, fatally stabbed Grace O’Malley-Kumar and Barnaby Webber, both 19, and Ian Coates, 65, during a stabbing spree in the city on 13 June 2023.
He admitted to manslaughter on the basis of diminished responsibility and was sentenced to indefinite detention at a high-security hospital.
The inquiry, which is being held in London, heard on Tuesday that, in May 2021, Calocane had attempted to hand himself in to MI5 at their headquarters at Thames House in central London.
