Northam Detectives have dismantled an established criminal network deeply rooted in the Northam and Toodyay townships.
The recent investigation by the Northam Detectives Proactive Team targeted the network that was directly responsible for the sale and supply of methylamphetamine.
To date, 13 people have been charged with over 146 drug related offences.
Operation Proscolex, which commenced in February 2019, is still ongoing with investigators constantly reviewing known associates of the criminal network to ensure every level of the network is held to account.
Over the past 18-months there have been several proactive, drug related operations targeting methamphetamine across the district.
During this period, a total of 62 people have been charged with over 395 offences.
Assets such as cars, jet skis and houses have been frozen and a large quantity of drugs have been seized.
Combined, the frozen assets and seized drugs are valued at several million dollars.
Multiple firearms and weapons including hand guns and high powered rifles were also among assets seized.
Wheatbelt District superintendent Martin Cope said the purpose of the operation is to reduce the sale and supply of methylamphetamine in the Wheatbelt region.
"We have a strong focus on disrupting the drug supply in the Wheatbelt and have increased sell and supply charges by 107-per-cent," he said.
"This effort will be ongoing and all drug dealers will be actively sought out and put before the courts to answer for the destructive impact they have on the community."
Northam Detective sergeant Anthony Pymm praised the support of the community by providing information to police.
Sergeant Pymm said Northam Detectives are committed in reducing other crimes that may be caused by illicit drug use such as volume crime offences, anti-social behaviour and domestic violence.
