Search continues for missing SA man

Police believe Scott Redman told friends and family he intended to travel to Western Australia

A search for a missing man, who fled from police more than a month ago after a high-speed car chase on South Australia's Eyre Peninsula, has continued.

About 50 local police, mounted officers and volunteers scoured an area of remote scrub west of Whyalla on Thursday in the hunt for Scott Redman.

Police believe the 19-year-old was in a car that was involved in a pursuit on the Eyre Highway near Kimba on April 21.

The pursuit was terminated due to safety concerns, with the black station wagon found on a dirt road 40km east of Kimba four days later.

Inspector Mark Hubbard said the terrain was challenging, with heavy bush in some patches, but police were preparing to cover up to 10 square kilometres.

"We have carefully searched a couple of key areas again, such as where the car was found and expanded out from there," he said.

Police believe Mr Redman told friends and family he intended to travel to Western Australia but there's no clear information on his location and fears are growing for his wellbeing.
