A woman in Austria was expecting a package of dresses she had ordered from a Dutch retailer. Two boxes from the Netherlands showed up at her door and while one of them contained her clothing, the other was packed with 25,000 tabs of MDMA worth a few hundred thousand dollars. From CNN:
The unnamed Austrian woman, 58, mistook the purple pills for decorative stones, police said, but on closer inspection her husband, 59, realized they were probably stimulants and returned the package to their local post office in Linz, Upper Austria…
"The (post) office was equally astonished, which is why the police, and subsequently the narcotics department of the City Police Command Linz, was informed."
Following an investigation by Linz's drugs squad it transpired that the package was intended for Scotland. Police Scotland and the UK's National Crime Agency (NCA) are jointly investigating the matter.
