In the police video, released today for the first time, the 33-year-old appears impassive as officers escort her in handcuffs from her home in Hereford.

After a trial lasting almost a year, Letby has been found guilty of murdering seven babies and seven counts of attempted murder.

She was also found not guilty of two counts of attempted murder. The jury failed to reach verdicts on six further charges of attempted murder.

The footage shows the moment detectives confronted her for the first time over their suspicions she may have been involved in the infants' deaths.

Police investigated suspicious deaths at the Countess of Chester Hospital's neonatal unit between June 2015 and June 2016.

Letby was first arrested on suspicion of murder at her home in Chester on 3 July 2018.

Police bodycam footage shows officers knocking on Letby's door before she lets them in.

Just over 10 minutes later, the video shows Letby, wearing matching blue jogging bottoms and a hoodie, being walked out of the house in handcuffs and put into a police car.

Later the same day, the 33-year-old was interviewed for the first time by detectives while in custody.

Speaking quietly, she can be heard explaining that arresting officers told her she had been linked to the case as she was present at the time many of the children had died.

When asked if she had any concerns about the rise in mortality rates in the neonatal unit, she said: "I think we'd all just noticed as a team in general, the nursing staff, that this was a rise compared to previous years."

Letby was later released but was arrested again in June 2019, when she was bailed pending further inquiries.

Three years after the investigation was first launched, Letby was re-arrested again on 10 November 2020.
