The Civil Nuclear Constabulary (CNC) welcomes new leadership to our Professional Standards Department (PSD) as two new officers join, bringing a wealth of experience.
Superintendent Alastair Stenner served for over 30 years with Gloucestershire Constabulary. During his career he has worked both in uniform and as a detective, on Counter Terrorism policing and most recently as the Head of Professional Standards, Vetting, Anti-Corruption and Public Feedback.
Reflecting on his approach to building standards, Alastair said: “How people treat one another is key to me. It is the foundation to how we build the right environment and culture. Alongside this, the organisation has to provide the right leadership and support so that all can flourish.
“I would like our PSD and Vetting work to be as open as possible, and I would ask that if anyone has any questions or needs any advice that they make contact with a member of the team.”
Chief Inspector Aidan Donohoe first served in the Royal Air Force before beginning his policing career at the City of London Police, then Thames Valley Police (TVP) where the majority of his 31-year career was spent.
He has served as an Authorised Firearms Officer, Operational Firearms Commander, and as an armed surveillance officer. Aidan joins us from his most recent role as Detective Chief Inspector, Head of Investigations for the force’s Professional Standards Department.
“My focus at TVP was always to try and support officers who had perhaps made genuine errors in judgement and who showed reflection and a willingness to change. I know the importance of professional development and I’m a strong advocate of giving opportunities to learn and improve.
“That said, for that minority who bring disgrace, at a time when trust is already low, I am committed to ensuring they have no place in policing.”
