Developments: 2. In late July 2026 Mexican federal authorities arrested Iker de Gandiaga, identified on social media as Iker "N", accusing him of running a large‑scale fuel‑tax evasion scheme that imported hydrocarbons, disguised them as lubricants, and sold them on the black market. The operation, carried out by the Gabinete de Seguridad and prosecuted by the Fiscalía General de la República (FGR), uncovered luxury assets including a penthouse, yachts and high‑end vehicles. De Gandiaga’s brother Iñaki and sister‑in‑law Natalia Balderón were also detained. Following the raid, investigators expanded the probe to include actress Montserrat Ramírez, the spouse of businessman Iker Andoni G., who is alleged to have facilitated money‑laundering for the same network. While no formal charges have been filed against Ramírez, the FGR is reviewing her bank accounts and the companies used to conceal illicit proceeds. The investigation underscores a broader effort by Mexican authorities to dismantle sophisticated fuel‑tax fraud operations and pursue all individuals linked to the scheme. ## Timeline ### 2026-08-04: Actress Montserrat Ramírez Investigated for Ties to Fuel Tax‑Evasion Network Mexican prosecutors are investigating actress Montserrat Ramírez for possible money‑laundering ties to a fuel‑tax evasion network led by her husband Iker Andoni G., after raids on the gang’s assets. 3 sources. https://clstr.news/cluster/actress-montserrat-ramrez-investigated-for-ties-to-fuel-taxevasion-network ### 2026-08-02: Mexico arrests alleged fuel‑tax evasion leader Iker de Gandiaga Mexican federal authorities detained Iker de Gandiaga, accused of leading a large fuel‑tax evasion scheme, seizing his penthouse, yachts and luxury cars; his brother and sister‑in‑law were also arrested. 3 sources. https://clstr.news/cluster/mexico-arrests-alleged-fueltax-evasion-leader-iker-de-gandiaga --- Cite as: Mexico fuel‑tax evasion crackdown.
