Colombia has extradited to the United States Dairy drug boss Antonio Usugu, known as Otoniel, Colombian President Ivan Duque Marquez announced.
Otoniel, in addition to being the most wanted and leader of the Del Golfo clan, is also the most dangerous trafficker of human beings in the world, writes BBC.
Otoniel was arrested in October after seven years in hiding and last month the Colombian Supreme Court upheld his extradition to the United States.
He is charged in the US with drug trafficking charge. Colombian authorities say the Otoniel clan smuggled between 180 and 200 tonnes of cocaine a year.
Announcing the extradition, Duque likened Otoniel to the infamous Colombian drug boss Pablo Escobar.
"This extradition shows that no one is above the Colombian state," he said in a message, accusing Otoniel of killing civil society leaders and police officers.
Prior to his capture, Otoniel was the most wanted man in Colombia, and the Colombian government offered a $ 800,000 reward for information leading to his whereabouts, while the United States offered $ 5 million for the same service.
Del Golfo operates in many provinces and has international connections, engaging in drug and human trafficking as well as illegal gold mining and extortion.
The clan is believed to have about 1,800 members, mostly recruited from far-right paramilitary groups. Del Golfo members have been arrested in Brazil, Argentina, Peru, Honduras and Spain. The clan has control over many routes used for drug smuggling from Colombia to the United States.
US authorities describe the clan members as "heavily armed" and "extremely violent". Otoniel was arrested in rural Colombia, where he was hiding, in the province of Antioquia, near the border with Panama.
500 soldiers and 22 helicopters took part in the operation to capture Otoniel.
