Warnings about Lucy Letby weren’t acted on - says doctor who worked with serial killer nurse

“One’s heart would sink when you saw Lucy Letby there again.” In his first interview consultant peadiatrician Dr John Gibbs who worked with the serial killer nurse tells Channel 4 News hospital managers were warned about the presence of Letby when several babies died. He told Clare Fallon he became 'very worried' about 'something abnormal that couldn't be medically explained' happening to babies on the unit. And says if his concerns and those of his colleagues had been listened to 'police would have been called in a lot earlier'. Lucy Letby has been found guilty of murdering seven babies and attempting to murder six others while working as a nurse at the Countess of Chester hospital. Medical director at the Countess of Chester, Dr Nigel Scawn, says they are “extremely sorry” that the crimes happened in their hospital and that “significant changes” have been made to its services since Lucy Letby worked there.
