The network of corruption in Mexican customs now affects the Ministry of National Defense. The newspaper Reforma revealed that the Attorney General’s Office is seeking to arrest three members of the Army for their alleged participation in the sale of 144 million liters of fuel at the customs in Matamoros, Tamaulipas.
The soldiers are on the run. They are part of a list of 13 people – including soldiers, sailors and businessmen – with arrest warrants. Seven have already been arrested.
The designated
The accused with military rank are Lieutenant Colonel Armando Barrera Trujillo and Blas Pedro Sarabia García, who were heads of customs between 2024 and 2026, and military police lieutenant Jorge García García, former deputy director of customs operations. Barrera and Sarabia have filed injunctions against the blocking of their bank accounts.
The plot was headed by Armando III Riestra Fernández, owner of Servicios Aduanales JR, imprisoned since January 2026 in the Altiplano prison. His company processed permits to import 144 million liters of fuel hidden as a calcium chloride solution. The importers were Jumandi Group and Ferroservicios.
“This criminal organization maintains a network of corruption that includes personnel from the military forces, such as the former head of the Matamoros customs, Armando Barrera Trujillo, Lieutenant Colonel of Sedena… and the current head, Blas Pedro Sarabia García,” Reforma cites in the arrest warrant.
The background of the case
Part of the fuel was smuggled after the Challenge Procyon ship was seized at Tampico customs. The ship declared additives, but was transporting hydrocarbons. That discovery uncovered a broader network: from June 2023 to March 2025, at least 69 illegal operations were coordinated in Mexican ports, with 564 million liters of illicit fuel.
Control of customs passed into military hands in mid-2020. Former president Andrés Manuel López Obrador justified the measure based on military honesty and efficiency. Successive corruption scandals have called that premise into question.
