The investigations are described as ongoing, with authorities working to identify the individuals involved and trace the origin, movement, and distribution of allegedly smuggled diamonds. The reports indicate that the probe is conducted by police, who seek evidence related to possible illegal trafficking and associated criminal conduct tied to the alleged jeweller connection. While the outlets summarise the scope of the raids and the existence of the investigation, details such as the number of suspects formally charged, the specific jeweller’s identity, and the estimated value of any seized goods are not included in the provided excerpts.
