Lucy Letby emailed police asking when she could be interviewed three months before she was arrested, a new documentary reveals.
The former nurse knew that her colleagues on the neo-natal unit at the Countess of Chester Hospital were being questioned by detectives about a spike in baby deaths and wanted to ‘alleviate her anxieties’, she said.
Detective Superintendent Paul Hughes, the senior investigating officer for Cheshire Constabulary, tells the Netflix documentary that Letby, 36, emailed him directly from her NHS email address quoting the name of the investigation – Operation Hummingbird – which was not in the public domain.
‘She wanted to know when we were going to speak to her,’ he said. ‘I found it interesting, I thought maybe she has got something to tell us.’
In the email, sent around April 2018, the convicted child killer asked him about ‘time frames’ and appeared to anticipate that she would need to ‘manage’ time off work to speak to officers.
‘It would also be beneficial for me to be able to share these potential time frames with my manager at work, as colleagues within my area of redeployment do not know my circumstances, or that I will be part of the investigation and a message within the team will need to be managed to account for my time off,’ she wrote.
Her email ended: ‘I would be very grateful for any information you can offer to help alleviate my anxieties.’
Senior managers had moved Letby from the neo-natal unit into an administration role at the hospital two years earlier, in July 2016, following doctors’ concerns.

But the public inquiry investigating Letby’s crimes heard that bosses kept her nursing colleagues in the dark about the exact reason for her redeployment – that she was suspected of harming and killing babies in her care.
Letby was eventually arrested at her home in Blacon, Chester – just over a mile from the hospital – around three months after writing the email, on July 3, 2018.
She was arrested twice more before being charged, and extensive footage of all three arrests also features in the 90-minute documentary, The Investigation of Lucy Letby, which is out today.
During the second arrest, Letby’s mother Susan, 65, can be heard crying and wailing, ‘Please, no, not again, no’ as officers arrive at dawn at her home, in a quiet cul-de-sac in Hereford, where she and husband John, 80, have lived for more than four decades.

Letby asks to say goodbye to one of her cats, then says to her parents: ‘You know I didn’t do it?’
They reply: ‘We know that.’ Letby can then be seen telling her sobbing mother ‘it’s alright’, before adding, ‘Just go in mum, don’t look mum, just go, just go in,’ as she is led in handcuffs to a police car.
On Sunday, Letby’s parents criticised the documentary as a ‘complete invasion of privacy’ and claimed they would not be watching because ‘it would likely kill us if we did’.

The film, made by ITN Productions, charts the story of ‘Zoe’, a full-term baby girl, whose name has been changed for legal reasons. She was the third child to be murdered at the Countess of Chester Hospital in a fortnight, in June 2015.
Speaking for the first time, Zoe’s mother explains the ‘panic, disbelief and confusion’ she and her husband felt after their daughter died unexpectedly soon after birth, and how she felt ‘relieved’ but ‘instantly broken’ when Letby was convicted of murdering her with an injection of air, following a ten-month trial, in August 2023.
The mother, whose identity has been digitally disguised to protect her anonymity, also hits out at the ‘disgusting’ attempts by campaigners, including Tory MP David Davis, to try to free Letby.
In February last year, Mr Davis opened a press conference, held by Letby’s new legal team to rubbish the medical science behind her convictions, by introducing Dr Shoo Lee, a Canadian neonatologist, as ‘the star of today’s show’.
The mother said: ‘This is not a show, there is no star, this is nothing to smile about. The audacity from a politician to introduce someone like this, it is disgusting.’
Letby is serving 15 whole-life terms after being convicted of murdering seven babies and attempting to murder seven more – one of whom she attacked twice – at the Countess of Chester Hospital between June 2015 and June 2016. She has twice failed to appeal her convictions.
In April last year her legal team lodged a file of new ‘expert’ evidence with the Criminal Cases Review Commission, the body that reviews potential miscarriages of justice, in the hope her case will be referred to the Court of Appeal a third time.
Inquests into the deaths of five of Letby’s victims, known as Baby C, E, I, O and P, are scheduled to be opened on Wednesday.
An inquest was previously held into the death of Baby A, in October 2016, while a hearing was previously opened and adjourned into the death of Baby D, in January 2016.
