Drug smugglers were unsuccessful in an attempt to use courier companies to get heroin into South Africa twice this week.

According to Ronnie Mamoepa, the South African Foreign Affairs spokesperson, someone pretending to be an official from the South African High Commission in Islamabad, Pakistan, went to a FedEx office in Islamabad on Saturday and tried to send a package to Johannesburg in an official High Commission envelope.

FedEx officials became suspicious when the person tried to use a false account number, evaded questions and left. The package was found to contain high-grade heroin.

In a subsequent incident, police reportedly seized a package containing 600 g of pure heroin being sent through DHL.
