In August 2022 the woman decided to make a complaint against the manager.
Wales has been told she was informed that the complaint was initially assessed as gross misconduct, but the manager was not suspended.
Four months later, after an investigation, it was formally assessed as misconduct – a less serious grading.
It is understood the complainant expressed her concern to investigators about this, suggesting it was not being taken seriously enough.
Gwent Police’s own disciplinary policy for police staff, last updated in 2017, gives sexual misconduct at work as an example of gross misconduct, which can result in dismissal if proven.
In February 2023, Ms Kelly wrote to the complainant saying the investigation was in its final stages and nearly all inquiries “are complete”.
But in May 2023, a second female colleague came forward with allegations of sexual misconduct, leading to the initial complaint being reassessed as gross misconduct and the manager being suspended on full pay.
Wales has been told a third allegation of sexual misconduct was then made against the manager in late 2023.
