Colombia's Supreme Court has approved the extradition of Dairo Antonio Úsuga, aka Otoniel. He is considered the leader of the Clan del Golfo, a large criminal network in Colombia. The US wants to try him for international cocaine trafficking.
Otoniel was arrested in October last year .
Úsuga's lawyers had argued that their client should face trial in Colombia before a special tribunal that will house participants in Colombia's civil war, which also includes FARC guerrillas.
Otoniel would also be willing to reveal details about cooperation between government officials and right-wing armed groups in exchange for preventing his extradition.
Colombia had put a $800,000 bounty on his head before his arrest, the United States $5 million.
In December, another Gulf clan leader was arrested .
The group is still active with an estimated 1,800 people in Colombia, mostly members of far-right paramilitary groups.
