A former female police officer allegedly sexually assaulted a woman in Melbourne's west multiple times.

Ex-Victoria Police LGBTIQ+ liaison officer Lucy Lenius fronted the Sunshine Magistrates' Court late last month after she was charged with four counts of sexual assault.

Lenius, who recently resigned from the Victoria Police, was a constable when she allegedly committed the offences in April 2022.

It's alleged Lenius placed her hand inside the woman's underwear and touched her vagina 'without her consent', the Herald Sun reported.

Lenius, who is fighting the charges, also allegedly grabbed the woman's buttocks and 'spread them apart'.

The matter will proceed to a contested hearing in November where the alleged victim and 1800RESPECT helpline worker will both give evidence.

Lenius had a previous run-in with the law after she fronted the Melbourne County Court appeal earlier this year for disclosing police information, specifically 'distressing' content the ex-cop had access to.

The court heard she was 'debriefing' and 'letting off steam' when she showed the 'traumatic content' - including a video - to a former partner.

Lenius was earlier found guilty in the Magistrates' Court but launched an appeal in the County Court.

The appeal failed and Lenius was re-sentenced to a $5000 fine without conviction after the court heard the offending occurred in a 'domestic context' and did not compromise any investigation.

Lenius served as a protective services officer (PSO) for three years and as a general duties officer for six years, before recently resigning from the force.

Lenius gave an interview with community newspaper Star Weekly in early 2023 in which she was asked why she took on the role of LGBTIQ+ liaison officer.

'As cliche as it sounds, I have a genuine desire to help people,' Lenius told the Star Weekly.

'I took on the role of LGBTIQ+ liaison to be an approachable police member for the community and help break the stigma.

'Being a LLO has given me the opportunity to attend LGBTIQ+ events and I have become a regular member of the Victorian Pride March.

'I am committed to creating a respectful and supportive environment for the community. Generally if the community is needing to contact police, it is not a good day for them. I want them to know we are here to assist if they need safety.'

The court previously heard Lenius made an application to the Police Association of Victoria for legal funding to be represented in her current case.

It remains unclear whether any funding has been approved.

Lenius, who plays footy in the Central Victoria Football League for the Wedge-Tailed Eagles, will next face court in November.
