One of Colombia's most wanted drug dealers Henry de Jesus Lopez Londono, known as Mi Sangre or My Blood, is to be extradited to the US.
US prosecutors requested the extradition of the alleged leader of Los Urabeños gang in late December 2012.
Lopez was arrested with his wife and ten bodyguards in Buenos Aires on October 30 and was due to be release on January 2, 2013 if no formal extradition request was filed.
The drug lord, who had been tracked by the US Drug Enforcement Administration, the Colombian police and the Argentine police forces for months, denies any accusations against him and insists he has been a victim of "a plot".
The police say that minutes before his arrest, Lopez had met a member of the Mexican drug cartel Los Zetas, for whom he provided much of the drugs.
