SECURITY · MEXICO
Key Facts
- —The country Mexico, the southern neighbour of the United States, where the Jalisco New Generation Cartel (CJNG) is one of the strongest criminal groups.
- —Why it matters The US Treasury sanctioned Iván Cazarín Molina, “El Tanque,” in 2024. It said fuel stolen by his network was resold into the US market, often in Texas.
- —Why now On Friday 9 October the security secretary said a leaked recording involving the Olán family, friends of the former president’s sons, is part of the investigation.
- —What happened At a hearing that began on Thursday 8 October, a federal judge ordered him held in pretrial detention at the Altiplano maximum-security prison.
- —What it means for you US persons are barred from dealing with him and the firms sanctioned with him. Fuel buyers near the border should screen suppliers.
- —Still open On Tuesday 13 October the judge decides whether he stands trial. Prosecutors have not said whether they are looking at Amílcar Olán.
A federal judge in Mexico has ordered Iván Cazarín Molina, known as El Tanque (“the Tank”), held in pretrial detention at the Altiplano maximum-security prison. The US Treasury sanctioned him in 2024 as a senior fuel-theft operator for the Jalisco New Generation Cartel (CJNG). Washington says fuel from his network reached US buyers, often in Texas.
The case widened on Friday 9 October. Security Secretary Omar García Harfuch, who runs Mexico’s federal security ministry, said a leaked phone recording tied to the family of businessman Amílcar Olán forms part of the investigation. Mexican media describe Olán as a close friend of the sons of former president Andrés Manuel López Obrador.
President Claudia Sheinbaum said the same day that nobody had briefed her on any link. She said the Attorney General’s Office would have to report one if it exists.

The Charges and the Next Hearing
Federal prosecutors from the Attorney General’s Office (FGR) charged him with organised crime aimed at drug offences. They added carrying a firearm and possessing ammunition reserved for the armed forces, according to El Universal and Proceso.
He appeared by video link from the offices of the FGR’s organised-crime unit in Mexico City, Proceso reported. El Financiero said the judge ruled the arrest lawful and granted the prosecutors’ request for detention.
The order is “prisión preventiva oficiosa,” a form of pretrial detention that Mexican law makes automatic for organised-crime charges. The defence asked for the legal deadline to be doubled so it could gather evidence.
The hearing therefore resumes on Tuesday 13 October. The judge will then decide whether to formally send the case to trial, a step known in Mexico as “vinculación a proceso.”
Until then he stays in Federal Prison No. 1, the Altiplano, in Almoloya de Juárez, State of Mexico. He is a suspect. No court has convicted him, and he is presumed innocent.
Who Is El Tanque
Federal forces detained him in Zapopan, part of the Guadalajara metropolitan area in Jalisco state. The army, the National Guard, the security ministry, the National Intelligence Centre and the FGR’s investigators took part. Officers seized a firearm, drugs and a vehicle.
Mexican officials say he ran CJNG operations in Veracruz, Tabasco, Oaxaca and Puebla. They link him to homicide, extortion, kidnapping, fuel theft, money laundering and drug trafficking.
El Universal reports he worked as a lieutenant to his brother, César Cazarín Molina, “El Tornado,” until the brother’s arrest in July 2013. Officials also accuse him of a role in a May 2015 attack on an army helicopter during an operation to capture the CJNG’s then leader, the late Nemesio Oseguera Cervantes, “El Mencho.”

On Tuesday 10 September 2024, the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned nine Mexican nationals and 26 Mexico-based companies in a CJNG fuel-theft network. It named him as a senior member reporting directly to El Mencho.
The Treasury said his fuel theft generated tens of millions of dollars a year. He tapped pipelines of Pemex, the state oil company, and stored fuel near the city of Veracruz in tanks holding millions of litres.
According to the Treasury, he sold the fuel through gas stations run by relatives and front persons. He also sold to third parties who resold it to the US market, often in Texas. Mexicans call stolen fuel “huachicol.”
The Olán Question
Amílcar Olán is a businessman whom Mexican outlets describe as a close friend of Andrés Manuel and Gonzalo López Beltrán. They are sons of López Obrador, who governed from 2018 to 2024 and founded the ruling Morena party.
García Harfuch spoke after a private meeting with the Political Coordination Board of the Chamber of Deputies. He said that, for now, the only material on Olán is a recording published by the press. “Everything forms part of the corresponding investigations,” he added, according to Sinaloahoy.
He said the FGR itself “will determine who else will be investigated in this case.” Radio station XEU reported his remarks in similar terms.
Sinaloahoy describes the recording as a leaked 2023 call. XEU reports that in it Luis Alberto Olán, Amílcar’s brother, says he knows El Tanque. Neither outlet says the call proves any crime.
At her Friday morning press conference, Sheinbaum said, “They have not informed me of anything about it.” She said Attorney General Ernestina Godoy had told her there is no investigation into López Obrador’s son, according to El Canal de las Noticias.
Neither Olán brother has been charged with any offence. Sheinbaum had earlier opened the door to a review of the businessman, as reported in Mexico: Sheinbaum Opens Door to Probe of AMLO-Linked Businessman Amílcar Olán.
What It Means for You
For US companies, the OFAC listing is the practical point. US persons are generally barred from dealing with him or the 26 listed firms, and any of their property in US hands is blocked.
Fuel distributors in Texas and other border states should check suppliers against the Treasury’s sanctions list. Washington has said stolen Mexican fuel enters the US market through intermediaries.
For investors, the case shows Mexico’s federal forces acting against targets Washington has named. That supports security cooperation at a time of close US scrutiny of the cartels.
The risk is political. Any inquiry touching friends of the former president’s family would be sensitive for Morena, and the FGR has not shown its hand. For travellers, nothing in the case changes the State Department’s existing advice for Jalisco or Veracruz.
What Is Not Known
It is not known whether the judge will send the case to trial on 13 October. The FGR has not publicly said whether it has opened any inquiry into Amílcar or Luis Alberto Olán.
No US extradition request has been made public. The Treasury gave only an estimate of the network’s income, so the full value of the stolen fuel is unknown. It is also unclear who now runs the network.
