Our correspondent Judith Morris is there for us tonight, Judith.

It's Sophie.

Three years after the police began their investigation into the deaths of babies at this hospital tonight, one of its former nurses is accused of multiple counts of murder and attempted murder.

The families of 18 babies are being given supporters.

They come to terms with this news.

Well, the nurse Lucy let me has been on bail for much of the last two years.

Cheshire police say their investigation has taken so long because it's been highly complex and extremely challenging, and they say that they've consulted a number of medical specialists to ensure that it's been as thorough as possible.

Lucy let be once posed for photos in her uniforms, telling her local paper in 2013 that she enjoyed nursing babies as she could see them progress on support their families.

Now she's suspected of murdering eight infants on trying to kill another 10.

The 30 year old worked in the neonatal unit of the Countess of Chester Hospital in 2017.

The hospital called in the police having become aware of a greater than usual number of baby deaths on babies at risk of dying between June 2015 on June 2016.

Lucy Lepi was first arrested in July 2018, her home nearby was sealed off and forensic officers searched the house and garden.

The nurse was arrested again a year later.

On then yesterday, she was arrested for a third time.

Cheshire police said they made the arrest based on further information that has been gathered as part of their ongoing investigation.

Tonight, Lucy, let be is being held in custody will appear before Magistrates in Warrington tomorrow.
