MEXICO CITY, Distrito Federal: Mexico said it had captured the leader of the country's Gulf drug cartel on Saturday, in a new blow to the criminal groups that have terrorized the country for years.
The interior ministry said in a brief statement that soldiers captured Mario Ramirez Trevino, described as "the head of a criminal organization that operated in the north of the country," in an operation on Saturday morning.
This is the second major success against Mexico's leading drug cartels for President Enrique Pena Nieto after the arrest last month of Miguel Angel Trevino, the head of the paramilitary Zetas cartel.
Pena Nieto, who took office in December 2012, has pledged to reduce drug-related violence that has resulted in more than 70,000 murders since 2006.
Ramirez Trevino was captured in Rio Bravo, a town on the border with Texas, according to a justice source in the northeastern state of Tamaulipas. Mexican military helicopters buzzed across the region on Saturday.
The United States had offered a $5 million reward for information leading to Ramirez Trevino's arrest. The Gulf cartel boss is charged with several US federal offenses, including facilitating the trafficking of cocaine and marijuana shipments from Mexico into the United States.
The interior ministry said it would hold a press conference on Sunday to discuss the details of his arrest.
Military checkpoints were set up outside Rio Bravo and the nearby border town of Reynosa, while soldiers and marines patrolled the streets, local media reported. Soldiers also took control of the international airport at Reynosa.
Ramirez Trevino, thought to be 51, became head of the once-powerful Gulf cartel after its former leader, Jorge Eduardo "El Coss" Costilla, was arrested in September 2012.
Reportedly a former drug addict, Ramirez Trevino -- also known as "El Pelon" ("Baldy") and "X-20" -- rose to lead the Gulf cartel group that controlled criminal activities in the key smuggling town of Reynosa, across the Rio Grande river from McAllen, Texas.
In recent months he reportedly asserted his leadership over the Gulf cartel organization by crushing a rival faction.
Ramirez Trevino also worked closely with the Gulf cartel's original leader, Osiel Cardenas Guillen, who is currently serving a lengthy prison sentence in the United States.
The Gulf cartel originally hired the Zetas -- elite anti-drug commandos that deserted and turned to the dark side -- to work as their enforcement arm. But the Zetas turned on their employers in 2010 and in a series of bloody turf battles took over most of their territory.
The Zetas now battle the western Sinaloa Federation for control of the major drug trafficking routes to the United States. The Sinaloa gang is headed by Joaquin "El Chapo" (Shorty) Guzman, Mexico's most wanted man.
The captured former head of the Zetas, Miguel Angel Trevino, alias "Z-40," is currently being held in a maximum security prison in Mexico.
The two high-profile successes in Mexico help balance out some major setbacks, including the surprise release on August 7 of jailed drug lord Rafael Caro Quintero, convicted of killing US Drug Enforcement Agency agent Enrique Camarena and his Mexican pilot Alfredo Zavala.
