A woman who was arrested on suspicion of data protection offences and misconduct while working for Cumbria Police will face no criminal action.
Her arrest related to concerns that information had been leaked to the media relating to the Police and Crime Commissioner on 10 April 2013.
The 50-year-old woman remains suspended from work.
Police will now begin a misconduct investigation in relation to any believed internal breach of the force's code of conduct.
