Bulgarian police charged three people and were searching for a fourth after a long-running investigation into drug trafficking and money laundering uncovered cannabis greenhouses inside a former zinc mine near Garlyano, at the foot of the Osogovo mountains a few kilometres from North Macedonia.[1][2]

Deputy director Emil Borisov of the General Directorate for Combating Organised Crime said the mine had high-tech infrastructure and was likely used for large-scale production meant for export.[1][2] So far officers had seized about 70 kg of drugs, 600,000 euros in cash and 600 rounds of ammunition.[1][2]

Authorities said they were still examining who owned the mine and how far the network reached; Reuters reported the inquiry could take months.[1][2]
