Evidence in first Lucy Letby trial was incorrect, CPS admits

Door swipe data showing which staff entered and exited baby unit was mislabelled' until retrial, CPS says

Evidence presented in the first trial of Lucy Letby showing which staff came in and out of the baby unit she worked on was incorrect, the Crown Prosecution Service (CPS) has acknowledged.

The nurse was convicted last year of murdering seven babies and attempting to kill six others at the Countess of Chester hospital in north-west England. Letby, the worst child serial killer in British history, is serving 14 whole-life sentences, meaning she will never be released from prison.
