A well-known senior Victoria Police officer is reportedly being forced out over claims of sexual harassment against two women under his command.

The unnamed officer has been told his contract will not be renewed when his current one ends, the Herald Sun reports .

At least two women, an unsworn public servant and an officer, who have worked under his command have told investigators he bullied and sexually harassed them.

Investigators from sexual harassment taskforce Salas believe several more complaints will be laid against the officer.

The officer is reportedly notorious among colleagues for his persistent sexual advances, mainly among younger women with a lower ranking.

Investigators from Taskforce Salas believe more than 3000 harassment and bullying complaints are being investigated following an independent probe launched by former Chief Commissioner Ken Lay.

However, none of those being investigated are believed to be as senior as the one referred to.

In the early 1990s, a younger police officer tried to confront the man being investigated after his girlfriend came home late claiming she had sex with him in a park after drinking.

However the officer was tipped off about the planned confrontation and stayed home to avoid ugly scenes in the workplace.

It is believed Taskforce Salas was created to work inside the force at the same time as the investigation by the Human Rights Commission and the Victorian Equal Opportunity Commission.

The investigation by HRC and VEOC included a survey, confidential interviews, site visits and submissions, with the survey drawing 5500 replies from police members.

In a force with around 11,000 members, the huge response flagged a serious hidden problem.

While the review was ordered by Commissioner Lay in an effort to expose the dark side of police culture in Victoria, it has been supported by his replacement, Chief Commissioner Graham Ashton.
