Armadale detectives are seeking information regarding an attempted armed robbery in Canning Vale last week.
At 3.15am on May 7, a 30-year-old-man was making a delivery to Livingston Marketplace on the corner of Nicholson Road and Ranford Avenue when a man approached him.
The approaching man asked him if he had any money and when he replied he did not, he was threatened with a knife.
The victim was able to get back into his vehicle and was chased by the offender and three other men in a white Ford Falcon station wagon through the car park.
The Falcon station wagon was believed to have been a 2002 or 2004 model.
Police would like to hear from anyone who was driving in the area between 3am and 4am and who may have captured a vehicle matching this description on a dash cam.
Anyone with information regarding the incident was asked to call Crime Stoppers on 1800 333 000 or report online at w
