During the trial of Lucy Letby, Prof. Peter Hindmarsh, a key expert witness for the prosecution, did not disclose that he was under investigation by his employer, University College London Hospitals NHS Trust, for serious concerns about his medical work, including allegations of patient harm. Cheshire police and the Crown Prosecution Service were also unaware of the investigation before Hindmarsh testified in November 2022. Hindmarsh provided crucial evidence regarding the alleged attempted murder of two babies by Letby. Legal experts suggest that Hindmarsh was obligated to disclose the investigation as it could potentially undermine his credibility. The undisclosed investigation raises concerns about transparency and the integrity of expert testimony in the case.
