SA police say drug ring shut down

Two South Australian bikie gangs were allegedly involved in an international drug ring which police say has been shut down following multiple arrests and drug seizures.

Operation Jackknife, which began in March 2013, involved officers from South Australia, the Australian Federal Police, the Royal Malaysia Police and Singapore Central Narcotics Bureau.

SA Assistant Police Commissioner Paul Dickson said SA police believed a number of people were travelling regularly to Malaysia to arrange the importation of pseudoephedrine and possibly methamphetamine.

He said a Malaysian-based drug distribution syndicate was dismantled in May.

"Authorities believe this syndicate was responsible for exporting controlled drugs and precursors from Malaysia to neighbouring countries and South Australia," he said.

The SA-based group was allegedly led by two bikie gangs, the Rebels and the Finks.

SA police have arrested 16 people, including members and associates of both gangs.

"We will be alleging this operation has brought to an end a joint enterprise by two outlaw motorcycle gangs (OMCGs) to bring a significant amount of methamphetamine into South Australia," he said.

""We know OMCGs don't hesitate to carry out violent crimes against one another, but this is clear evidence that when there is money and drugs involved, they'll put aside their differences and work together for the proceeds of crime."
