HOUSTON, Texas — The lawyer of a powerful Mexican drug cartel leader who is now in U.S. custody pushed back Sunday against claims that his client was tricked into flying into the country, saying he was “forcibly kidnapped” by the son of Joaquín “El Chapo” Guzmán.

Ismael “El Mayo” Zambada had eluded authorities for decades and had never set foot in prison until a plane carrying him and Joaquín Guzmán López, a son of notorious drug kingpin “El Chapo,” landed at an airport in Santa Teresa, New Mexico, near El Paso, Texas, on Thursday. Both men, who face various U.S. drug charges, were arrested and remain jailed.

Frank Perez, Zambada’s attorney, said his client did not end up at the New Mexico airport of his own free will.

“My client neither surrendered nor negotiated any terms with the U.S. government," Perez said in a statement. “Joaquín Guzmán López forcibly kidnapped my client. He was ambushed, thrown to the ground, and handcuffed by six men in military uniforms and Joaquin. His legs were tied, and a black bag was placed over his head.” Perez went on to say that Zambada, 76, was thrown in the back of a pickup truck, forced onto a plane and tied to the seat by Guzmán López.

Known as an astute operator skilled at corrupting officials, Zambada has a reputation for being able to negotiate with everyone, including rivals. He is charged in a number of U.S. cases, including in New York and California. Prosecutors brought a new indictment against him in New York in February, describing him as the “principal leader of the criminal enterprise responsible for importing enormous quantities of narcotics into the United States.”

Removing him from the criminal landscape could set off a turbulent internal war for control over the cartel, as has occurred with the arrest or killings of other kingpins. Experts say it could also open the door for a more violent, younger generation of Sinaloa traffickers to move up.

Perez declined to offer much more comment beyond his Sunday statement, saying only that his client had been traveling with a light security detail and was set up after being called to a meeting with Guzmán López.

Perez’s comments were first reported by the Los Angeles Times.

A spokesperson for the U.S. Justice Department did not immediately return an email seeking comment Sunday on Perez's claims. Court records did not list an attorney for Guzmán López, whose father is serving a life sentence in a U.S. prison.

According to a U.S. law enforcement official familiar with the matter, Zambada was duped into flying into the U.S.

The cartel leader got on an airplane believing he was going somewhere else, said the official, who spoke on the condition of anonymity because they were not authorized to discuss the matter. The official did not provide details such as who persuaded Zambada to get on the plane or where exactly he thought he was going.

Zambada appeared in federal court in El Paso on Friday morning, where a judge read the charges against him and informed him of his rights. He is being held without bond and has pleaded not guilty to various drug trafficking charges, court records show. His next court hearing is scheduled for Thursday, Perez said.
