The public is being urged to keep their eyes peeled for the Porsche driver at the centre of a crash on a Melbourne freeway that led to the deaths of four police officers.

Victoria Police has released images of Richard Pusey who is wanted on two outstanding warrants for contravening a court order.

Pusey, who uses they/them pronouns, is about 190cm tall with short brown hair, but is known to change his appearance.

The 45-year-old is also known to travel across the state by both vehicle and public transport, police say.

Pusey was jailed in 2022 for 10 months for using a carriage service to cause offence, over the use of graphic pictures.

Four Victoria Police officers died when a truck crashed into them on the side of the Eastern Freeway, where they had pulled over Pusey, who escaped injury.

Graphic images from the 2020 crash were attached to a complaint which Pusey sent to the Australian Financial Complaints Authority in 2021.

Pusey had lodged a complaint after PSC Insurance Brokers, underwritten by Dawes Motor Insurance, refused to indemnify their 2016 Porsche 911, which was significantly damaged in the crash.

They made a $2.2 million insurance claim over the car, which was valued at $415,000.

Pusey was acquitted of a second charge, which alleged they had posted a Google review about Porsche Centre Melbourne using a separate image of the crash as the profile picture.

Anyone with information about their whereabouts is urged to contact the Crimestoppers website, or call 1800 333 000.
