Henry de Jesus Lopez Londoño, one of Colombia’s most-wanted drug-trafficking suspects, has been captured in Buenos Aires, the National Police said.

The 41-year-old Lopez Londoño, a top boss of the Los Urabeños drug gang, and a bodyguard were arrested at a restaurant in the Argentine capital thanks to information that Colombia’s Dijin police agency provided to Argentine authorities.

Prior to his arrest on Tuesday, Lopez Londoño was “the biggest supplier of cocaine” to Mexico’s Los Zetas drug cartel, Colombian National Police director Gen. Jose Roberto Leon said in a press conference Wednesday.
