Vienna drug investigators ended an inquiry that ran from autumn 2025 into 2026 with the seizure of about 30 kilograms of cocaine and six arrests, according to Christoph Hackl of the Vienna criminal investigation office.[1] Investigators focused on a 43-year-old Serbian man who allegedly directed the business from a rented bunker flat and garage in an apartment building in Liesing.[1] Officers arrested the 43-year-old shortly after he took a delivery, catching him handing about 600 grams of cocaine to two alleged sub-dealers, a 36-year-old Iraqi and a 39-year-old Serbian, and also detained a 31-year-old Croatian courier at Spielfeld, a 38-year-old Austrian held primarily over threats to his ex-wife, and a 31-year-old Austrian alleged cannabis-resin supplier.[2]

The follow-up house search of the 43-year-old recovered the remaining cocaine from the delivery plus about 27 kilograms of cannabis resin.[2][3][4] Police list total seizures as 30,156.3 grams of cocaine, 27,457.6 grams of cannabis resin, 435.6 grams of marijuana, 16,850 euros in cash and a vehicle with a smuggling hide.[2][4] The ORF account summarises the result as over 30 kilograms of cocaine with a street value of about three to 3.5 million euros, plus 27 kilograms of cannabis resin, a five-figure sum of cash and three vehicles.[1]

Police say the investigation ran since November 2025 in coordination with the Vienna prosecution and the drugs had been moved from Valencia in a professionally converted car with a hidden compartment behind the rear seat.[2][3] In March 2026 investigators arrested the alleged cannabis-resin supplier linked to the 43-year-old, finding cannabis resin, cannabis herb and packaging material for about 37 kilograms of cannabis resin that had already been opened and had presumably been circulated.[2][3][4]

The main suspect took over a 20-kilogram cocaine delivery that had been brought directly from Valencia in Spain to Vienna in a prepared smuggling car.[3] Officers stopped the suspected 31-year-old Croatian courier from leaving the country at Spielfeld and found another ten kilograms of cocaine in a professional hidden compartment in his vehicle.[3] Officers found a loaded handgun alongside drugs and cash when arresting the 38-year-old suspect.[3]
