Guardia Civil officers, as part of Operation Golalde, have seized 322 guns, including four machine guns and seven submachine guns, as well as 50,000 cartridges. Four people were arrested for allegedly forming part of a network selling the weapons to a wide variety of criminals, say officers.
The operation centred on Madrid, Asturias and Cantabria, where eleven homes and premises linked to the group were searched.
The group traded weapons from Spain and other countries, including decommissioned guns that they adapted to make work again. As the serial numbers hadn't been removed and they weren't registered with the authorities, it was easier to channel the weapons into the black market.
