Drugs and cash have been seized.
The officer in charge of Karratha detectives, Detective Senior Sergeant Carlos Correia said this did not mark the end of police efforts to thwart drug dealing in the area.
“Our efforts don’t stop here,” he said.
“We won’t tolerate illicit drugs being dealt in our local community and we will continue our efforts targeting those who are involved.
“It’s information from the public that helps us conduct these operations and we encourage the community to continue reporting any suspicious behaviour to Crime Stoppers.”
