Montemorelos search yields 303,000 liters of suspected hydrocarbon

Reporting and context

Federal prosecutors seized approximately 303,000 liters of suspected hydrocarbon liquid during a court-authorized search in Montemorelos, Nuevo León, according to Infobae México's account of an FGR statement. The search took place at a property in the Las Puentes ejido, where investigators also found storage containers, industrial equipment and chemical products.

Infobae México reported that no arrests were made. The investigation remains open to establish the liquid's origin and exact nature and to determine who may be responsible for possible hydrocarbon offenses. Authorities had not identified a particular person or group in connection with the site.

The seizure inventory included six storage tanks, two frac tanks, 229 intermediate bulk containers, a tank semitrailer, a flatbed trailer and a forklift. Investigators also secured four pumping units, an electricity generator, a concrete mixer and documents considered relevant to the case.

A pallet held 50 sacks containing a white powder. Its composition and any connection to the suspected offenses remained unconfirmed, pending forensic analysis. The report does not identify the powder as a drug.

FGR investigators and forensic personnel carried out the inspection with specialized Pemex staff. The army, National Guard and Montemorelos municipal police secured the perimeter while the search proceeded.

For scale, the report cites an FGR total of 4,702,850 liters of hydrocarbon seized in 15 operations across eight Nuevo León municipalities during 2026 to date, compared with 3,111,908 liters in all of 2025, an increase of about 51 percent. These are broader totals, separate from the approximately 303,000 liters reported at Las Puentes; the figures should not be added together.
