WEDDERBURN police are searching for a man who drove at two policemen in Korong Vale last month.
Central Goldfields Crime Investigation Unit Detective Senior Constable Steve Atkinson said the two policemen jumped out of the way of the speeding vehicle to avoid being hit.
The man was "desperate" to behave in such an aggressive manner, he said.
He said the two policemen approached the man, who was squatting on rural land about three kilometres south of Korong Vale, about 11.20am on June 28.
He said the man was aggressive to the policemen, who retreated and called for backup.
"The members had concerns for their safety at the time due to the male being very aggressive towards police when they first approached him," Detective Senior Constable Atkinson said.
"He was obviously desperate, for reasons unknown, to behave like he did when police were simply there to speak to him about a trespassing matter."
The man then got into his ute, which had two dogs in the back, and sped towards the two policemen, who were standing near their cars at the entrance of the property.
The policemen, fearful for their safety, jumped out of the way of the ute, which swerved at the last minute to prevent a crash.
The man then drove towards Wedderburn.
Investigators have released a simulated image of a man they believe may be able to assist with their inquiries.
He is described as being about 170 centimetres tall with a medium build.
He has black, curly, neck-length hair and unshaven, dark whiskers.
He was wearing a camouflage jacket, jeans and had bare feet at the time of the incident. The ute he was driving was a white Mitsubishi Triton displaying South Australian number plates similar to VDO602 or VOD602.
One dog was light brown in colour while the other dog was similar to a white Golden Retriever.
