Mexican authorities showed the world's most-wanted drug lord, Joaquin "Shorty" Guzman, to the public at Mexico City airport.
"Shorty" runs Mexico's infamous Sinaloa Cartel and is believed to command groups of hitmen from the US border into Central America.
Mexico's most wanted man, drug kingpin Joaquin "Shorty" Guzman, has been captured, President Enrique Pena Nieto confirmed, announcing a major victory for the government in a long, brutal drugs war.
Pena Nieto confirmed the arrest via Twitter on Saturday and congratulated his security forces.
The capture is a huge political victory for Pena Nieto, who took office in late 2012. "Guzman is the jewel in the crown, the most wanted drug boss in recent years and in that sense this is a great success," said Jorge Chabat, an expert on drug trafficking at the CIDE research center.
Mexico's most wanted man, drug kingpin Joaquin "Shorty" Guzman, has been captured in Mexico by US and Mexican law enforcement officials, sources told Reuters, in what would mark a major coup in a grisly fight against drug gangs.
"Shorty" Guzman runs Mexico's infamous Sinaloa Cartel and is believed to command groups of hitmen from the US border into Central America.
The United States had placed a $5 million bounty on Guzman's head and authorities in Chicago last year dubbed him the city's first Public Enemy No.1 since gangster Al Capone.
"Shorty" Guzman escaped a Mexican prison in a laundry cart in 2001 to become the country's most high-profile trafficker.He was indicted in the United States on dozens of charges of racketeering and conspiracy to import cocaine, heroin, marijuana and crystal meth.

Vigilante groups have taken over eight towns in southern Mexico, in an attempt to provide citizens with protection from organised crime.
About 500 armed men spread out in the state of Guerrero on Friday, setting up check points along the Mexico-Acapulco highway where they stopped drivers.
The men are members of a vigilante "self-defence" group and believe the Mexican government has failed to provide adequate protection for its people.
Convicted killer Edgar Tamayo, a Mexican national condemned for the 1994 murder of a Houston police officer, has been put to death by lethal injection in Texas despite diplomatic pressure from Mexico, which denounced his execution as a violation of international law.
Tamayo, 46, who was denied an 11th-hour stay of execution by the U.S. Supreme Court, was pronounced dead at 9:32 p.m. local time at a state prison in Huntsville, Texas, according to officials at the Texas Department of Criminal Justice.
Mexico has strongly objected to the scheduled execution in Texas on Wednesday of a Mexican convicted of killing a U.S. police officer, arguing that by executing him, the United States would be in "clear violation" of international treaties.
Edgar Tamayo was convicted of shooting dead a Houston police officer in 1994 when he was in the United States illegally. But Tamayo was not informed of his right, enshrined in an international treaty known as the Vienna Convention on Consular Relations, to diplomatic assistance.
In 2004, the United Nations' International Court of Justice ordered the United States to reconsider the convictions of 51 Mexicans, including Tamayo, who had been sent to death row without being informed of their consular rights.
Rare conjoined grey whale twins have been found dead, washed ashore in a Mexican lagoon.
In video footage released by the Mexican Natural Protected Areas Commission, the twins - conjoined at the stomach - are seen in the Ojo de Liebre lagoon in the north-western state of Baja California Sur, which opens out into the Pacific Ocean.
Scientists from the commission told local media they believe the dead calves could have died as a result of a miscarriage. The commission say this could be the first recorded case of conjoined whale twins.
Mexico has issued a public alert after a truck carrying potentially "extremely dangerous" radioactive material was stolen on Monday, according to Mexican authorities.
The vehicle was carrying cobalt-60 from a hospital in the northern city of Tijuana to a waste storage site.
A statement from the UN nuclear watchdog, the International Atomic Energy Agency (IAEA), said:
At the time the truck was stolen, the source was properly shielded. However, the source could be extremely dangerous to a person if removed from the shielding, or if it was damaged.
The Mexican authorities are currently conducting a search for the source and have issued a press release to alert the public.
Hundreds of clowns have gathered in Mexico City for a "laugh-a-thon" to protest against gang violence in the country.
Around 500 entertainers from across Latin America laughed and played an assortment of comedy instruments for 15 minutes.
They were also protesting against reports that a gunman had disguised himself as a clown to kill a drug lord last week.
"We want a little bit of peace. We spread happiness, laughter, smiles. That's why we're clowns," said clown Esteban Garcia.
The rally took place on the penultimate day of the Latin American clown convention.
