In April 2014, a raw coltan cargo of questionable origin was arrested in Piraeus Port from local custom authorities. Although the cargo was officially shipped through a Cypriot intermediary company, later evidence later linked it with Nova Dies network and illegal stockpile. However, the cargo in the meanwhile was temporarily released and then transported to the Republic of Macedonia before its true origin could be affirmed. A relevant incident also happened in July 2014 in Piraeus, when a coltan cargo was first arrested, then released as legitimate and finally proven –after a specific procedure of sample identification- as mined from a conflict zone in DRC, however at the time of the discovery the main cargo had already disappeared. In 2013, Nova Dies affiliates were connected with incidents of coltan imports in Europe from illegal mines in Colombian Amazon areas and the Guaviare River, controlled by local drug cartels. The company, also partially belonging to Colombian interests, has been investigated for assisting Colombian narco-traffickers to legitimize drug-related money by complex commodities derivatives multinational transactions along with layering structures.
