A vehicle search during INTERPOL’s Operation Neptune VII border checks in Montenegro led to the seizure of 15 kg of marijuana.[1] Operation Neptune VII ran from July to September 2025 as a border-security operation coordinated by INTERPOL with Europol, Frontex and the World Customs Organization, targeting Mediterranean maritime routes, airports and land borders.[1] The operation ran for about two weeks in each of the 20 participating countries.[1]

INTERPOL said Operation Neptune VII produced a total of 220 kg of marijuana, alongside silver bullion, USD 130,000 in cash and stolen luxury vehicles.[1] Montenegro was one of 20 participating countries, alongside Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Spain and others.[1]

The operation’s main stated aim was counter-terrorism border control, and INTERPOL said it also produced significant seizures tied to other serious crimes.[1] INTERPOL said drugs, high-value goods and cash are often used to fund criminal and terrorist activity.[1]
