Mexican police say they have captured the country's most wanteddrug lord, Servando "La Tuta" Gomez.
Mr Gomez, leader of the Knights Templar drug cartel, was arrested in Morelia in Michoacan state without a shot fired, police officials said.
Previously a school teacher, he became one of Mexico's most powerful drug lords and took control of Michoacan.
His capture is a coup for the government of Enrique Pena Nieto in its fight against the drug cartels.
A police spokesman told local media the arrest followed months of intelligence work in the region.
Police reportedly seized nearby properties in the weeks leading up Mr Gomez's capture and arrested several of his associates.
There are lots of theories as to the origin of the nickname La Tuta, but it seems that for most it's just another mystery.
While La Tuta's capture may be a coup for the administration of Enrique Pena Nieto, the fallout in the state of Michoacan is not clear. It is a poor and violent part of the country, the battleground between drugs cartels and vigilantes trying to oust them.
As one security expert told me, this was a man who was not just in charge of a drugs empire, he wanted political power too - and in politics you gain as many enemies as you do friends.
Perhaps that is what led to the net closing in in the end?
