The leader of a major drug trafficking organization known as the “Oficina de Envigado” was arrested Wednesday in the northeastern city of Medellin, Colombian authorities said.

Calling the arrest of Erikson Vargas a “death blow” to the crime group, President Juan Manuel Santos said at a news conference that he would be extradited to the United States.

Police said he was taken into custody at a farm near Medellin in an operation in which another member of Vargas’ group was killed and several others were also arrested.

He was wanted on charges of conspiracy to murder, drug trafficking, and extortion.
