Prosecutors weigh new charges against Lucy Letby as investigations expand

Prosecutors are reviewing evidence that could lead to additional charges against Lucy Letby, the former neonatal nurse convicted of murdering seven babies and attempting to murder seven others during her time at the Countess of Chester Hospital. The Crown Prosecution Service (CPS) confirmed it had received new material from Cheshire Police, which has been investigating further incidents connected to Letby's career.

Expanded investigation into baby deaths

Cheshire Police’s ongoing probe, dubbed Operation Hummingbird, was launched in 2017 following a surge in unexplained deaths and collapses in the neonatal unit of the Countess of Chester Hospital, where Letby worked between 2015 and 2016. The investigation now spans back to 2012, covering Letby’s earlier training and employment at Liverpool Women’s Hospital.

The force recently submitted a comprehensive file of evidence to the CPS for review, though details on the number and nature of potential new charges remain undisclosed. A CPS spokesperson stated that any decision on further charges would be made independently and based on the available evidence in accordance with legal standards.

Legal and medical challenges to convictions

Letby, now serving 15 life sentences, has consistently denied her crimes. Her legal team, led by barrister Mark McDonald, has pursued multiple avenues to challenge her convictions. Earlier this year, they filed an application with the Criminal Cases Review Commission (CCRC), supported by a panel of 14 international neonatal and pediatric experts. The panel’s report argued that none of the babies were intentionally harmed, raising questions about the evidence presented at Letby’s trial.

The CCRC is currently reviewing the application but has not indicated when a decision might be expected. Former Health Secretary Jeremy Hunt has also called for an urgent re-examination of the case, citing "serious and credible" concerns raised by the expert panel.

Arrests of hospital managers and public inquiry

In a related development, Cheshire Police announced the arrest of three former senior managers at the Countess of Chester Hospital on suspicion of gross negligence manslaughter. The individuals were released on bail as investigations continue.

Meanwhile, a public inquiry led by Dame Caroline Thirlwall is examining the circumstances surrounding Letby’s crimes, as well as broader issues of hospital culture and governance within the NHS. The inquiry’s findings are expected to be published in early 2026.

Letby’s case remains one of the most chilling in modern British history, with ongoing legal and medical debates likely to shape its legacy.
