Updated Thursday 3.30pm: The investigation into suspended Lincolnshire Police chief constable Neil Rhodes will be led by the chief constable of Greater Manchester Police Sir Peter Fahy.
Mr Rhodes was suspended by Lincolnshire Police and Crime Commissioner Alan Hardwick over “potential conduct matters” on February 26.
The case was referred to the Independent Police Complaints Commission which has today (Monday) decided to pass the matter back to Mr Hardwick after finding no serious corruption or misconduct.
A commission spokesman said: “The Independent Police Complaints Commission has now completed a detailed assessment of the referral of a potential conduct matter concerning the force’s temporary chief constable, Neil Rhodes.
“The outcome of the assessment is that we are satisfied the matter requires investigation but does not amount to serious corruption or misconduct which would merit an Independent Police Complaints Commission investigation.
“The decision to return this matter for local investigation has been communicated to the Lincolnshire Police and Crime Commissioner. It will now be for him to determine the way forward.
“The Independent Police Complaints Commission has advised that if further concerns come to light in the course of the investigation the matter should be re-referred to us.”
Mr Hardwick welcomed the decision, adding: “The decision made by the Independent Police Complaints Commission not to carry out their own investigation is understandable and in line with previous determinations they have made on chief officer conduct matters.
“I will be conducting my own independent and rigorous local investigation into the potential conduct matters that were raised.”
Last week acting chief constable Alec Wood said he and the rest of the force did not know why Mr Rhodes had been suspended.
