The temporary Chief Constable of Lincolnshire Police has been suspended by the county's new Police and Crime Commissioner.
PCC Alan Hardwick says he sent acting Chief Constable Neil Rhodes home after he was "made aware of potential conduct matters" involving the senior officer.
Mr Rhodes took over as temporary head of Lincolnshire Police when the former Chief Constable Richard Crompton retired in March last year.
