One of Colombia’s most wanted drug dealers, Henry de Jesus Lopez, has been arrested in Argentina.
He is alleged to be a leader of the Urabenos gang, which controls much of the drug trade in northern Colombia.
Colombian President Juan Manuel Santos has made the fight against criminal gangs such as the Urabenos one of his government’s priorities.
President Santos, via his Twitter account, thanked the Argentine authorities for their help.
“Another blow against the Bacrim (criminal bands) and drug-trafficking,” Mr Santos wrote.
Lopez, 41, is reported to have fled to Argentina several months ago.
