An ornate gold belt was seized in 2021 and the rest of the pieces were seized in recent weeks. Police said the investigation continued.

The pieces are being studied by Spain’s National Archeological Museum and the country’s Cultural Heritage Institute.

Interior ministry attachés in Albania, Bulgaria, Cyprus, North Macedonia and Ukraine helped with the investigation, police said.
