British nurse Lucy Letby's parents, Susan Letby and John Letby, slammed Netflix's upcoming true crime documentary The Investigation of Lucy Letby, claiming the project is an "invasion of privacy" after their daughter was arrested. After a trailer was released for the project, Susan and John said that they were not informed that the unseen footage - including scenes from inside of their longtime home - would be featured in the documentary. "The previous programs made about Lucy, including Panorama and the almost nightly news showing her being brought out handcuffed in a blue tracksuit, are heartbreaking for us," the couple told The Guardian in a statement on Sunday, February 1. "However, this Netflix documentary is on another level." The couple added that they "will not watch" The Investigation of Lucy Letby. "It would likely kill us if we did," they said.

In the trailer, officers were seen arriving at Susan and John's home in Hereford while Lucy was staying with them in June 2019. Authorities were then shown entering her bedroom and she sat up in bed. Lucy appeared confused as one officer told her she was being arrested on suspicion of murder and attempted murder, and she was led out of the room in her pajamas. "Heaven knows how much more they have to show. All this taking place in the home where we have lived for 40 years," Susan and John told the outlet, adding that they live "in a small cul-de-sac in a small town where everyone knows everyone." "It is a complete invasion of privacy, of which we would have known nothing if Lucy's barrister had not told us," Susan and John said. The parents also asked, "Why is Paul Hughes [an investigating officer in Letby's case], with whom we always cooperated fully, allowed to show the world what took place in our house that morning and Netflix not even have the decency to tell us?" Netflix and ITN Productions did not immediately respond to Us Weekly's request for comment regarding Susan and John's statement.
