Bolivian authorities have arrested Sebastián Marset, an alleged Uruguayan drug trafficker described as one of South America's most wanted criminals, according to the country's interior ministry.

Marset, 34, is accused of trafficking large quantities of cocaine from South America to Europe. He is wanted by the United States on money laundering charges and is being extradited there, Bolivian officials said.

The alleged drug kingpin also faces accusations of ordering the murder of a Paraguayan prosecutor who was shot dead while honeymooning on a Colombian beach in 2022. The prosecutor's killing highlighted the reach of organized crime networks across South America.

Marset's arrest represents a significant development in regional efforts to combat drug trafficking operations that have established extensive networks spanning multiple countries. His alleged organization is believed to have been involved in moving tonnes of cocaine through international smuggling routes.

The extradition to the United States indicates the international scope of the case against Marset, with authorities in multiple countries coordinating efforts to prosecute high-level drug trafficking suspects.
