Mexican President Andres Manuel Lopez Obrador today asked the United States for a “full report” for the arrest Thursday in Texas of two leaders of Mexico’s powerful Sinaloa drug cartel, including its co-founder Ismail Sabada Garcia, also known as “El Mayo,” during an operation in which Mexico was not involved.

“The US government needs to deliver a full report, not just general statements, we need to have information, there needs to be transparency,” said Lopez Obrador during his daily press conference.

The two leaders of the multi-national cartel were arrested when their private plane landed in Texas on the US side of the Mexican border after a brazen sting operation, according to US media citing law enforcement sources.

Joaquin Guzmán López, son of notorious cartel leader Joaquín Guzmán Loera, or “El Chapo,” had convinced “El Mayo” to board a plane that was supposed to be bound for southern Mexico, but the plane was actually heading north and landed in El Paso, United States, according to Fox News.

The son of “El Chapo,” the drug lord who co-founded the Sinaloa cartel and is currently serving a life sentence in the United States after being convicted in 2019, lured “El Mayo” onto the plane “under false pretenses,” according to senior U.S. officials cited by the New York Times.

The Justice Ministry said the two men were taken into custody.

Both face prosecution in the United States for their roles in the manufacture and trafficking of fentanyl, a powerful synthetic opiate and “the deadliest drug threat our country has ever faced,” US Attorney General Merrick Garland said.

The arrest of “El Mayo” strikes “at the heart of the cartel responsible for most of the drugs, including fentanyl and methamphetamine, that kill Americans from one ocean to the other,” said Anne Milgram, the head of the DEA , of the US Federal Drug Enforcement Administration.
