Police in Switzerland have seized 14 kilograms of heroin worth over CHF2 million ($2 million) during a cross-border investigation carried out with the German authorities.
Swiss police said on Monday that the drugs had been confiscated in the north-eastern town of Kreuzlingen, in canton Thurgau, located on the shores of Lake Constance at the German border.
During an earlier operation in November, border guards found and seized 4kg of heroin in a car belonging to a 42-year-old Turkish man from Germany.
A subsequent joint police investigation with the authorities in the German city of Cologne led to the late April arrest of a 48-year-old Albanian and another Turkish national, 43, who kept a car in Switzerland. Investigators found 10 kg of heroin inside his vehicle, which was confiscated.
The two Turkish nationals are part of an international network of drug traffickers, according to the local authorities of Swiss canton Thurgau.
All three individuals have been placed in preventive detention.
