Overview
- Cheshire Constabulary arrested and bailed three former senior leaders from the Countess of Chester Hospital on suspicion of gross negligence manslaughter over neonatal unit fatalities.
- The arrests fall under Operation Duet, launched as a corporate manslaughter probe in October 2023 and expanded in March 2025 to cover individual gross negligence offences.
- The CPS has received a full evidence file from police and is reviewing potential further charges against Lucy Letby for additional baby deaths and non-fatal collapses.
- Investigators continue to examine incidents at both the Countess of Chester and Liverpool Women’s Hospital neonatal units between 2012 and 2016.
- Both the corporate and gross negligence manslaughter investigations remain active with no set timescales following Letby’s 2023 conviction for seven murders and seven attempted murders.
