Senior police are among the worst offenders for harassing and menacing LGBTI officers, with slurs such as "faggot" common in police stations, and officers receiving threats of violence from their colleagues.

A scathing report into Victoria Police's culture found the force still tolerates a "culture of hypermasculinity" that fuels aggressive remarks and sexual harassment.

The Victorian Equal Opportunity and Human Rights Commission report, commissioned by Victoria Police and to be released on Friday, revealed incidents reported by LGBTI officers that show a pattern of overt homophobia.

One LGBTI police officer said a fellow officer told him, "All gays should be gassed in the chamber like the Nazis," and another said, "they should be taken out the back of the station and shot in the head".

A gay senior constable said a high-ranking sergeant pulled him aside on a night shift to tell him he could not work with a "poofter", while another officer said they were "ridiculed, harassed and mocked every shift".
