A member of the senior leadership team at the Countess of Chester Hospital has been re-arrested as part of an ongoing investigation surrounding corporate and gross negligence manslaughter linked to the actions of former nurse Lucy Letby. This arrest by Cheshire Police occurred on April 22, 2023, following the execution of a search warrant.
Details of the Investigation and Arrest
The individual arrested has not been publicly named but is believed to be one of three senior leaders detained in June 2025. This latest arrest is related to suspected perverting the course of justice. Letby, who was convicted in 2023, is currently serving a total of 15 whole-life orders for the murders of seven infants and the attempted murder of seven others at the neonatal ward between June 2015 and June 2016.
Operation Duet: A Closer Look
The inquiry, known as Operation Duet, focuses on whether the hospital’s management failed to protect vulnerable patients by ignoring signs of harm while Letby was employed. Following Letby’s convictions, Cheshire Police expanded their investigation to include corporate manslaughter and gross negligence manslaughter, beginning in October 2023.
- Date of Re-Arrest: April 22, 2023
- Investigation Name: Operation Duet
- Charges Against Letby: Convicted of seven murders and seven attempted murders
- Timeframe of Crimes: June 2015 – June 2016
Ongoing Investigations
Cheshire Police are reviewing cases of both fatal and non-fatal incidents involving infants at the neonatal units of the Countess of Chester Hospital and Liverpool Women’s Hospital during Letby’s employment from 2012 to 2016. The definitions of the inquiries underline severe failures, where corporate manslaughter points to organizational negligence, while gross negligence manslaughter charges individuals within that organization.
Next Steps and Timeline
Both components of the investigation remain open, with no fixed timeline for conclusions. Additionally, Lady Justice Thirlwall is expected to release the findings from a related public inquiry in 2026. As the investigation continues, further developments are anticipated regarding the responsibilities of hospital leadership in light of Letby’s actions.
