Head of Mexican Gulf Cartel Captured

Mario Ramirez Trevino, aka X-20


Mexican troops have captured one of the country's most wanted drug-gang leaders.

Mario Ramirez Trevino, known as X-20, is said to be the head of the cocaine and marijuana-smuggling Gulf Cartel.

Security was stepped in the north of the country to prevent rival gangs fighting to expand their influence into the void left by the capture.

It is the second high-profile arrest since President Enrique Pena Nieto came to power last December.

Correspondents say that has led to questions about how different Mr Pena Nieto's strategy is to his predecessor Felipe Calderon's.
