Nottingham attacks: 'I was foolish to trust legal system', says Barnaby Webber's mother
Barnaby Webber, 19, was one of three people killed in a series of knife attacks in Nottingham last June. Valdo Calocane was sentenced to a high-security hospital after he killed Mr Webber, another 19-year-old student, Grace O'Malley-Kumar, and school caretaker Ian Coates.
