Attorney general Victoria Prentis asks court of appeal to review hospital order handed to Calocane, who killed three people

The families of the three people stabbed to death in the Nottingham attacks last year have welcomed a court of appeal review of the “unduly lenient” sentence of the perpetrator, Valdo Calocane.

The killer was sentenced to an indefinite hospital order last month for the attacks on university students Barnaby Webber and Grace O’Malley-Kumar, both 19, and a school caretaker, Ian Coates, 65, in the early hours of 13 June last year.
