Mexico’s Navy says it has arrested the alleged successor of a commander the United States has indicted. The accusations are allegations, and no court has ruled.
Mexico’s Navy says it arrested a suspected regional boss known as El Semáforo in Tuxtepec, Oaxaca. The El Semáforo arrest was announced on Wednesday, 28 October, and he is presumed innocent.
Officials describe him as the successor of El Tanque, whom the US Justice Department indicted on 22 October. The Justice Department calls him a commander of the Jalisco New Generation Cartel (CJNG), a US-designated terrorist organization.
What the Navy Says Happened
Marina, the Mexican Navy, announced the arrest of Carlos “N”, alias “El Semáforo” (the Traffic Light). Mexican officials give only a first name and an initial for suspects before a court rules.
The Navy named a woman, Ana Gabriela “N”, as an alleged logistics operator for the same group. It said she was detained in the same operation.
The arrests took place in San Juan Bautista Tuxtepec, and the statement does not give the hour. The Navy worked with the federal Security Ministry and the Criminal Investigation Agency of the federal prosecutor’s office.
Both detainees were flown by Navy helicopter to the naval air base in Veracruz, then by plane to Mexico City. They were placed at the disposal of a federal prosecutor, who will decide their legal status.
Who the Authorities Say He Is
Officials describe him as a regional boss at the second level of his group’s structure. They link him to Boca del Río and San Andrés Tuxtla in the state of Veracruz, and to the Oaxaca border area.
Authorities say he took over after the arrest of Iván Cazarín Molina, alias El Tanque, in Zapopan, Jalisco, on Monday, 5 October. The US Treasury has linked El Tanque to drug trafficking, extortion and homicide, which are allegations.
The Navy calls him an alleged regional chief of a criminal group. One account quotes the Navy tying the arrests to actions against the CJNG, but other accounts of the statement do not.
What Was Seized
The Navy says it seized drugs, weapons and grenades in Tuxtepec. It also listed four vehicles, six motorcycles, two all-terrain vehicles and one property.
The statement estimates the total value at MXN 8,837,000 (about US$474,000, at 18.65 pesos per dollar on 29 October). It gives no count of firearms or amount of drugs.
Officials say these two arrests add to 16 other alleged members of the group detained earlier in Veracruz and Oaxaca. The other 16 are not named.
How This Links to the El Tanque Case
Mexican forces arrested El Tanque on 5 October, and a US grand jury in Washington indicted him on 22 October. The Justice Department says he faces at least 40 years and up to two consecutive life terms if convicted.
The US Treasury sanctioned him on 10 September 2024 over an alleged fuel-theft network. Earlier coverage details the arrest and of the US indictment.
What It Means for US Readers
The US Secretary of State labelled the CJNG a foreign terrorist organization on 20 February 2025. That widens legal risk for anyone dealing with the group.
Travellers should check State Department advisories for Oaxaca and Veracruz before booking. Investors with Mexican energy or logistics exposure should note that the Treasury calls fuel theft the largest non-drug cartel revenue source.

What Is Not Known
The Navy has not said how it located him, and the statement gives no arrest hour or date. No court has set charges, and a prosecutor has yet to decide his legal status.
Some accounts link him to attacks on federal agents and a kidnapping attempt. Only one account says so and the statement does not, so it is left out.
One account gave a full name and age for him, but no official source confirms them, so they are omitted. The Navy does not say whether he has a lawyer or has responded.
What Comes Next
A federal prosecutor will decide the legal status of both detainees, as the statement says. No court date or charges have been announced.
The arrest does not mean the group is finished, and officials have not said whether other leaders remain at large. It also does not mean the United States has charged him.
