Northern Territory Police have arrested 40 Mongols members and associates, including some of the bike gang's Darwin heavyweights, following an extended operation targeting the group.
NT Police said Operation Morley has been investigating the Mongols for their involvement in the alleged supply and distribution of methamphetamine in the Darwin region since September 2021.
The operation, according to police, has "destroyed" the Mongol leadership, with the arrests of the national president, the president, vice-president and sergeant-at-arms of the Mongols' Darwin chapter.
Nick Forbes, the gang's alleged national president, was arrested in the Northern Territory in October last year.
NT Police said they used a "number of investigative capabilities" which resulted in the arrests.
The 40 members or associates have been charged with offences including commercial drug supply, extortion and aggravated assault.
Following a series of raids, police said they had also seized 1.2 kilograms of methamphetamine, 6.8 kilograms of cannabis, over $500,000 cash and 34 firearms.
NT Police said further arrests and charges are expected in the coming weeks.
NT Police Detective Superintendent Lee Morgan said a "Mongols national run" from Alice Springs to Darwin during October opened a variety of leads.
"[It] enabled us to get a great deal of information, intelligence and evidence," he said.
Superintendent Morgan said there continued to be concerns about the ongoing impacts of crimes stemming from bikie gangs on the streets of Darwin.
"You might have a young kid in a nightclub buying ecstasy, ending up in hospital, maybe dying. There's a good chance those drugs were initiated through an outlaw motorcycle gang," he said.
"We will continue to be ruthless in our approach in combating these offences and combating these people.
"They are a blight on society, and we will do everything in our power to continue to eradicate them".
NT Police said it was now finalising the 18-month operation.
