The former chief constable of Northumbria Police said she was “shocked” by a report that alluded to sexist behaviour towards her.
Sue Sim retired last month having been cleared of misconduct charges in relation to how she dealt with some staff.
She says the formal report into her alleged misconduct revealed she was treated differently by some senior officers, simply because she was a woman.
Mrs Sim told BBC Radio 5 Live: “I thought we had moved on significantly, but as you are aware there was an investigation into my conduct, and one of the things that I was absolutely shocked by is that, during the investigation, one of the things they found was that my senior male colleagues treated me differently than they would have done a male chief constable.”
A Northumbria Police spokesman said: “It is disappointing and a real shame that Mrs Sim has chosen to express these views and to do so in this way.
“We do not accept the criticism that she has directed at Northumbria Police, an organisation that she personally was in command of for five years.”
