We reported last June that Lucy Letby was arrested for the second time in relation to an investigation into baby deaths at The Countess of Chester Hospital's neonatal unit between 2015 and 2016.
At that time, she was suspected in eight deaths and six attempted murders out of the 17 deaths and 16 "non-fatal collapses" that were being investigated.
She was arrested for the third time yesterday, and has been charged with eight counts of murder and 10 counts of attempted murder. She is scheduled to appear at the Warrington magistrates court tomorrow.
"The Crown Prosecution Service has authorized Cheshire police to charge a healthcare professional with murder in connection with an ongoing investigation into a number of baby deaths at the Countess of Chester hospital,” a statement for the Cheshire police said.
He also indicated that the parents had been updated concerning the arrest.
Detective Chief Inspector Paul Hughes was quoted by Sky News as calling the case "highly complex and very sensitive" saying that despite the fact that the investigation began more than three years ago, the investigation "is very much active and ongoing. There are no set timescales and we remain committed to carrying out a thorough investigation."
