Police are still hoping the public will come forward with information or dashcam footage that will help their investigation into the robbery of a truckie on the Eyre Highway earlier this month.
Just before 2.30am on Friday, September 15, police were called to Eyre Highway at Coorabie, after a report that a truck driver had been robbed.
A B-double had broken down on the highway earlier in the day and the driver was waiting for parts to be delivered to continue his journey.
The stranded truckie alleges that a man approached the truck and knocked on the window. He presented a machete and threatened the driver before stealing cash and the keys to the truck, said police.
The man ran towards the back of the truck and drove off in a dark coloured beat-up Holden sedan without registration plates, last seen heading north-west on the Eyre Highway.
The suspect is described as being about 180cm tall, with a strong build, wearing a balaclava and a hat.
The truckie was not physically injured as a result of the incident, added police.
Anyone with information that may assist with the investigation or motorists travelling on the highway who may have dashcam footage is asked to contact Crime Stoppers South Australia on 1800 333 000 or online at crimestopperssa.com.au.
