Mexican security forces say they have captured the leader of a major cocaine-trafficking cartel - the second alleged drugs boss to be held in a government crackdown in just over a month.
Mario Ramirez Trevino - known as X-20 or 'The Bald One' - was held in the northern Tamaulipas state by the military according to media reports.
Mr Ramirez had only recently become leader of the Gulf Cartel after former boss Mario Cardenas - alias 'Fatso' - was caught in September.
The Gulf Cartel's power has waned in recent years in a feud with Mexico's most brutal gang the Zetas, which began life providing protection to the cartel's operations in north-east Mexico.
Washington had offered a $5m bounty for Mr Ramirez, blaming his cartel for controlling most of the cocaine and marijuana trafficked to the US from Matamoros in Tamaulipas state.
Mexican marines last month arrested the leader of the Zetas, Miguel Angel Trevino, near his hometown of Nuevo Laredo on the US border.
More than 70,000 people were killed during former president Felipe Calderon's six-year offensive against drug cartels and over 6,000 have died since President Pena Nieto took office in December.
President Nieto has continued to fight cartel violence since coming to power.
