Postal drug ring based in Adelaide

A man and woman have been charged over an Adelaide-based drug trafficking operation.

The 22-year-old male and 21-year-old female are accused of trafficking a large commercial quantity of a controlled drug after a kilogram of Pentylone was discovered in a consignment from overseas.

The drugs, equivalent to 10,000 street deals of ecstasy, were first spotted in Melbourne but destined for South Australia, police say.

The man was refused police bail to appear in Adelaide Magistrates Court on Tuesday while the woman has been granted police bail to appear in court in November.
