The National Desks at Eurojust opened linked cases to provide operational and legal assistance, including the creation and funding of a JIT between the Belgian and Dutch authorities, with the involvement of Eurojust and Europol. During a joint action day supported by a coordination centre at Eurojust, coordinated searches and arrests were executed. The Dutch-Belgian JIT continued to work together during the prosecutorial phase and included a financial investigation that led to the tracing and seizure of assets.

Six coordination meetings took place at Eurojust to agree on the common investigation and prosecution strategy and to exchange evidence. Eurojust provided a formal legal opinion on a possible ne bis in idem issue in the Belgian and Italian criminal proceedings. With the support of Eurojust, cross-border cooperation took place with Germany, Romania and Italy.
