Notorious Colombian cocaine trafficker Dairo Antonio Úsuga, also known as Otoniel, has pleaded guilty to drugs charges in a US court.

Otoniel was the leader of Colombia's most powerful criminal gang for more than nine years. The 51-year-old agreed to hand over $216m (£173m) in drug proceeds.

He was arrested in his Colombia hideout in October 2021 and extradited to the US last year, where there was a bounty for information leading to his capture.

On Wednesday, Otoniel pleaded guilty to "running a continuing criminal enterprise" as well as to drug smuggling and distribution charges.

One of the prosecutors described Otoniel as "the most significant Colombian narcotics trafficker since [the leader of the Medellín cartel] Pablo Escobar".

The US Drug Enforcement Administration said he was "one of the most violent and prolific drug traffickers in the world".

He now faces a mandatory minimum sentence of 20 years and up to life in prison. The United States had offered a bounty of $5m (£4m) for help finding him.
