A senior Metropolitan Police officer called a colleague an "Asian babe" in "racially and sexually explicit messages", a misconduct panel has found.
Former Detective Sergeant Stephen Redgewell, 54, who resigned from the force in November 2018, after the allegations emerged, would have been sacked if he were still a serving officer.
The Mirror reported that he had sex with a 'dominatrix' in the headquarters of the Met Police Federation in Bromley.
Redgewell was found to have "abused his position" as deputy general secretary and treasurer of the Met Police Federation, which represents rank-and-file officers, by "behaving in a predatory manner" towards the woman he was assisting.
