A 29-year-old woman living in Swieqi is being held by police after she was caught receiving a postal package containing 600 grams of suspected cannabis.
Police said on Saturday that anti-drug squad officers had worked together with customs officials to arrest the woman.
The package was sent from the USA, the police said.
The woman is currently being held for questioning and could be arraigned in court tomorrow, to face charges of having imported and trafficking the drug over the past months.
