A married consultant described as the 'boyfriend' of baby killer nurse Lucy Letby is being investigated over details shared with her about a child she tried to kill.
The pair exchanged more than 1,300 flirtatious messages in three months while they worked together at Countess of Chester Hospital - also going on walks, meals and taking day trips to London.
Convicted serial killer Letby, 35, is serving life behind bars for murdering seven babies and attempting to murder seven more between June 2015 and June 2016.
Although they denied having an affair, the prosecution at her trial described the unnamed medical professional as the serial killer's 'boyfriend'.
A note with the doctor's name was also found by police in Letby's home, with love heart sketches scrawled across it.
