TWO men were arrested and charged after armed robberies were committed in Barragup, Lakelands, Munster and Spearwood.
Regional Investigations Unit detectives arrested the two men as a result of their investigation.
They allege on May 18 in the evening, the men entered a service station in Barragup armed with a tomahawk and a baseball bat, and threatened staff.
They were given a sum of cash before leaving in a car.
A short time later, the same men robbed a service station in Lakelands – also armed with a tomahawk and baseball bat.
The men fled the store after being given a sum of cash and cigarettes.
In the evening on May 26, detectives found out about two aggravated armed robbery offences, within close proximity to each other and within minutes of each other.
These offences occurred at service stations in Munster and Spearwood.
With the assistance of Mandurah police, Rockingham detectives and other police officers, Regional Investigations Unit detectives apprehended the two men in Greenfields.
A search warrant on a residence in Windermere Way, Greenfields resulted in the discovery of stolen property.
A 21-year-old Greenfields man and a 20-year-old Dawesville man were charged with three counts of aggravated armed robbery and attempted aggravated armed robbery.
They are due to appear in the Perth Magistrates Court today.
