The BBC revealed Josef Easom-Cooper and Junior Dietlin, who have paranoid schizophrenia, stabbed members of the public in in four separate attacks in February and April 2023. Calocane, who also has paranoid schizophrenia and was in the care of the trust, stabbed to death Barnaby Webber, Grace O'Malley-Kumar and Ian Coates on 13 June 2023.

Dr Susan Elcock, deputy chief executive and executive medical director at Nottinghamshire Healthcare, said: ‘Firstly I apologise to those impacted by these incidents and for any aspect of our care which was not of the high standard our patients, their families and our communities deserve.

‘Whilst we are unable to comment on individual cases due to patient confidentiality, I want to assure people that following any serious incident there is a robust review process which includes an initial management review to ensure any immediate learning and action takes place. This is then followed by a full investigation and a clear quality improvement plan detailing any learning and subsequent actions required.

‘We have also implemented the new national patient safety incident response framework which further strengthens this review and learning process. We know that it is really important for patients and families to be fully involved and I am confident our approach now ensures this happens, and that issues are addressed swiftly and transparently with patients involved in every aspect of their care.

‘Above all, we remain fully committed to ensuring all our patients and their families receive the care they deserve, and our communities feel safe.'
