One officer was demoted from a leading senior constable to senior constable, another was fined $1000 and transferred out of the district .

Charges against a third officer were not proven.

Victoria Police's ethic standard detectives launched an investigation after the coroner was presented with allegedly misleading sworn evidence in relation to the death of Jodie Laurie, 23, at the Warrnambool police cells in 2003.

Ms Laurie killed herself in the cells after being arrested for shoplifting. An inquest into her death was held in 2005.

Three officers were investigated and charged over their evidence at the inquest in relation to travel arrangements on the night of Ms Laurie's death.

They were charged with discipline offences and were the subject of hearings.

The demoted officer is understood to have admitted telling the inquest he drove a colleague home after Ms Laurie's body was found, but he drove the colleague to a social gathering at the home of another police officer.

A whistleblower complained about the evidence given to the inquest in 2007.

Coroner Jennifer Coate previously wrote to Ms Laurie's family, telling them misleading evidence had been presented to the inquest.

In the letter she wrote that an assistant commissioner had advised her that he received a complaint in October 2007 from the Office of Police Integrity alleging police had given misleading evidence relating to travel arrangements to the coroner during the inquest.

It is understood Ms Coate said the coroner's findings had been reviewed but the inquest would not be reopened because the misleading evidence had no impact on the findings.

Members of Ms Laurie's family were unhappy with the inquest process.

They said if police lied about such minor detaiks, other evidence by the officers also had to be considered questionable.
