Lucy Letby interviewed in prison over more baby deaths and collapses

Child serial killer Lucy Letby has been interviewed in prison over the alleged murders of babies at two hospitals.

Cheshire Police said it had "recently" spoken to the former nurse as part of an ongoing investigation into more baby deaths and non-fatal collapses.

Letby, 34, from Hereford is currently serving 15 whole-life orders for the murder of seven babies and attempted murders of seven others, with two attempts made on one child.

She has lost two bids to appeal her convictions, the most recent in October. She can now only challenge her convictions if the Criminal Cases Review Commission refer those cases back to the Court of Appeal.

In a statement, Cheshire Police said: "We can confirm that, following agreement, Lucy Letby has recently been interviewed in prison under caution in relation to the ongoing investigation into baby deaths and non-fatal collapses at the Countess of Chester Hospital and the Liverpool Women's Hospital."

It said further updates would follow at the "appropriate time".

Liverpool Women's Hospital is where Letby trained as a student. She is understood to have carried out two work placements at the hospital between October and December 2012, and January and February 2015.

Detectives have previously said they are reviewing the care of the more than 4,000 babies Letby looked after during her career.

The case is also currently being examined as part of the Thirlwall Inquiry, which is looking into the events surrounding her crimes.

The inquiry previously heard that the dislodgement of breathing tubes, which was how Letby tried to kill Child K, generally occurs on less than 1% of shifts.

However, it happened on 40% of shifts that Letby worked when she was a trainee.

Giving evidence to the Thirlwall Inquiry, neonatal clinical lead Dr Stephen Brearey said: "I think it's likely that Letby didn't start becoming a killer in June 2015, or didn't start harming babies in June 2015."

The inquiry is expected to sit until early 2025.
