The police watchdog has removed some staff from investigating the case of Calocane after they allegedly gave officers details of their investigation. Calocane, who has paranoid schizophrenia, fatally stabbed Mr Coates, Mr Webber and Ms O'Malley-Kumar on 13 June 2023, and was sentenced to a hospital order in January 2024. The IOPC said it had commissioned an independent external review, with sources claiming the staff accused of making the comments were not the decision-makers about the case or about disciplinary action. An IOPC spokesperson said: "We are aware of allegations made about IOPC staff by Leicestershire Police officers who are subjects of an IOPC investigation. "The allegations involved comments alleged to have been made about that investigation.
