'Unprecedented' - New Lucy Letby Netflix documentary reveals unseen footage during arrest and questioning

The new documentary will feature never-before-seen footage.

A new documentary about the investigation into convicted child killer Lucy Letby will reveal never-before-seen footage of the former nurse during her arrest and questioning.

The film - titled The Investigation of Lucy Letby - will be released on Netflix, and feature new testimony from police and contributions from the mother of one of the victims. It is the first time a family member involved in the prosecution has spoken in a documentary.

A new trailer, released today (January 22), sees the case described as “once-in-a-lifetime” and opens with the statement: “This footage has never been revealed publicly.”

A teaser for the documentary adds: “Unprecedented access, footage and insight into the conviction of a British neonatal nurse who was found guilty of murdering seven babies.”

Letby, 36, is serving 15 whole-life terms for the murder of seven babies and attempting to murder seven more, with two attempts on one of her victims, at the Countess of Chester Hospital’s neonatal unit in 2015 and 2016.

The Crown Prosecution Service (CPS) announced this week that she will face no further charges over additional deaths and collapses of babies that were investigated by police.

11 additional charges were considered by the CPS in relation to a total of nine babies, with both murder and attempted murder considered in respect of two infants.

Of the 11 charges considered, eight potential offences of attempted murder and one of murder related to the Countess of Chester Hospital, while one offence of attempted murder and one of murder were linked to one child at Liverpool Women’s Hospital.

The CPS said following a “thorough review” of evidence provided by Cheshire Constabulary, “no criminal charges should be brought”.

Lady Justice Thirlwall’s inquiry report into how Letby was able to commit her crimes on a hospital neonatal unit is due to be published this year.

The Investigation of Lucy Letby will land on Netflix on February 4, 2026.
