Mexico Zetas leader Miguel Angel Trevino captured
Mexican marines have captured one of the world's most notorious drug-gang leaders in a raid near the US border.
Miguel Angel Trevino Morales, 40, head of the Zetas Cartel, was intercepted with two lieutenants in a pick-up truck near Nuevo Laredo.
Mexican officials said he had eight guns and $2m (£1.3m) in cash.
Trevino Morales, infamous for his brutality, was wanted on both sides of the border for ordering massacres and running drugs on a global scale.
He took control of the Zetas following the death of group founder Heriberto Lazcano in October 2012.
The government of Enrique Pena Nieto has said that its strategy on the drug war would involve a shift away from high profile arrests towards a broader reduction of violence on Mexico's streets. For every drug cartel leader who is captured, the government has said, there is another to take his place.
But, nevertheless, they will be privately overjoyed at bringing down such an important drug lord as Trevino Morales - especially without even having fired a shot.
Unlike other top members of the Zetas, Trevino Morales did not come from the military. But he appeared to make up for his civilian background by specialising in a particularly sadistic form of violence against his victims.
His is the highest-profile arrest since President Enrique Pena Nieto came to office last December.
Mr Pena Nieto promised to change the policy of the previous government by tackling cartels through law enforcement on a local level rather than the capture of big-name targets.
Ex-President Felipe Calderon had deployed the army across the country and pursued cartel leaders.
Although the policy eliminated many senior criminal figures, it also created power vacuums that helped fuel the violence.Fall of the Zetas
Trevino Morales, known as "Zeta-40", was captured outside Nuevo Laredo, near the US border at dawn on Monday, government spokesman Eduardo Sanchez told a news conference.
"Three people in the truck were detained by ground troops, who had arrived to support the naval forces, who had carried out the detention via the helicopter. Not a single shot was fired," he said.
The authorities say they acted after a surveillance operation lasting several months.
The Zetas began as the enforcement arm of the Gulf Cartel, another powerful criminal gang.
They were made up of defectors from an elite military unit and quickly became known for their brutality.
Trevino Morales was unlike most of the Zetas because he was a civilian who worked his way up through the ranks.
The Zetas split from the Gulf cartel in 2010, sparking brutal turf wars across northern Mexico.
By 2012, they were reputed to be the largest and most powerful cartel.
Mexico media reaction
- El Universal charts the rise of Trevino Morales: "His power led him to challenge even the US authorities, orchestrating a series of killings of rivals on American soil"
- El Sol de Mexico gives a rundown of the country's most wanted, placing Trevino Morales at number two behind Joaquin 'El Chapo' Guzman, head of the Sinaloa cartel
- The Excelsior reports claims that Trevino Morales was betrayed by members of the Zetas, and that the cartel is disintegrating
But expert Alejandro Hope says the arrest is another step towards the destruction of the Zetas as a coherent organisation.
"There will still be people who call themselves Zetas, bands of individuals who maintain the same modus operandi," said Mr Hope, a former member of Mexico's domestic intelligence service.Most wanted
Analysts say Trevino Morales' younger brother, Omar, has been one of his closest lieutenants and may try to position himself as successor.
The BBC's Will Grant in Mexico City says the authorities fear that the arrest could lead to a period of in-fighting between different Zeta factions.
Miguel Angel Trevino Morales
- Began life of crime as a teenager running errands for Los Tejas gang
- Joined the Gulf cartel in 1990s and became notorious for brutal murders involving burning his victims to death
- Began the push for Zetas' split from the Gulf cartel in 2007; became overall Zetas leader in 2012
- US authorities put out $5m reward for information leading to his capture
- Charged with ordering the kidnapping and killing of 265 migrants in two massacres, among other offences
Trevino Morales is believed to be responsible for ordering two notorious attacks on migrants from other Latin American countries.
In 2010, he allegedly ordered the torture and murder of 72 Central American migrants as punishment for their refusal to act as drugs mules.
A year later, he apparently oversaw the massacre of almost 200 immigrants for similar reasons.
Before he became the group's overall leader, Trevino Morales co-ordinated the gang's important Nuevo Laredo drug corridor into the US, the region in which he was finally apprehended.
He is also believed to have controlled a squad of killers who operated in the US state of Texas.
The US authorities had offered $5m reward for any information leading to his capture, making him one of the world's most-wanted drug traffickers.
