There are calls for Instagram to remove an account belonging to Richard Pusey, after revelations the Porsche driver has been posting online rants about the Eastern Freeway tragedy that made him a household name.
The 43-year-old filmed and mocked four police officers as they lay dying on the side of the road in April last year.
They were struck by a truck after pulling Pusey over for speeding.
He spent ten months in prison following the incident but in recent weeks has been repeatedly referencing the tragedy, the victims and their families on social media.
In a post last month, the disgraced mortgage broker uploaded a photo of Senior Constable Lynette Taylor's widower, Stuart Schulze, with the caption: "'Diabolical act' says Stuart who has never contacted me or read my statement. Sorry to attempt to seek instructions from the last person alive Stuart. Sorry to attempt to ask your wife if she had anything to say to you or your family and then freak out."
Pusey also posted a video to a private TikTok account, apparently filmed from a car driving along the road where the officers were struck, with the caption: "Eastern Freeway sunset."
Other posts include anti-police and anti-jail rants and videos from inside his home, as he plays loud music with bright coloured strobe lights.
Former Victoria Police Commissioner Kel Glare told 9News Pusey needed to be "pulled into line".
"He's got no respect for police, no respect for the law, no respect for the public at large and no respect for the victims of his actions," Mr Glare said.
Pusey, who is currently on bail for unrelated charges, has been contacted for comment.
Instagram has also been contacted for comment.
