Driver terrorises bushwalkers at Collie

Senior Sergeant Mike Dean said the pair were walking along the Bibbulmun Track Wednesday afternoon when a car without a number plate described as being "grey with a blue door and no exhaust" raced past them, spraying dust.

He said the vehicle turned around and drove back down the walking track towards the bushwalkers, who were so frightened they ran into the bush.

They later the reported the incident to police.

Inquiries are continuing.
