A 47-year-old Iranian man and three Spaniards from the same family -- a father in his 70s, a son in his 40s, and a daughter in her 40s -- were arrested and charged with attempting to smuggle dual-use material, membership in a criminal organization, and money laundering. The Iranian remains in detention while the Spaniards were released but restricted from leaving the country.
The arrests followed an investigation into the Spanish family's import firm last year by the Civil Guard, which uncovered the illegal importation of two metal-forming industrial machines from the United Kingdom into Spain. The authorities believe the equipment was destined for Iran, in violation of international sanctions against Iran for its nuclear and missile programs.
A Civil Guard captain, who spoke to CNN on the condition of anonymity, said the machines could be used to aid uranium enrichment.
