Three former Countess of Chester executives arrested

Cheshire Police arrest three former senior leadership-team members of the Countess of Chester Hospital on suspicion of gross negligence manslaughter in connection with the deaths. The investigation was widened to include gross negligence manslaughter in March 2025. The three were subsequently bailed pending further enquiries. The investigation, known operationally as Operation Duet, is institutional and runs separately from the Letby convictions and the CCRC review.
