Bolivian authorities arrested Attorney General Roger Mariaca after the United States accused him of taking bribes to facilitate drug trafficking and revoked his visa earlier this week.

Mariaca was arrested Wednesday night in Santa Cruz as part of a broader investigation into an alleged criminal network operating within Bolivia’s justice system, according to Interior Minister Marco Antonio Oviedo. Fourteen people, including four prosecutors and six employees of the Public Prosecutor’s Office, were arrested in the operation.

Authorities also raided Mariaca’s home and other prosecutors’ offices. Oviedo said four people were caught attempting to remove bundles of cash from Mariaca’s residence inside an ambulance early Thursday.

Video released by Bolivia’s Interior Ministry showed police removing stacks of cash from panels inside the ambulance.

Oviedo accused the Public Prosecutor’s Office under Mariaca of operating as a criminal organization that protected and facilitated drug trafficking. Bolivian authorities have described the arrests as part of a crackdown on alleged corruption and drug-trafficking ties within the justice system.

The arrest came just two days after the U.S. State Department revoked Mariaca’s visa. The department accused him of accepting bribes to facilitate drug trafficking and helping violent criminals evade justice. Mariaca has denied the allegations.

The investigation also involves alleged ties to Uruguayan drug trafficker Sebastian Marset, who was captured in Bolivia earlier this year and transferred to U.S. authorities. Reuters reported that authorities released recordings in which Marset allegedly implicated Mariaca and referred to him as a friend.

Mariaca’s attorney, Romel Ipamo, said his client would cooperate with the investigation. The Attorney General’s Office said Luis Montano Morales, the next-most senior prosecutor, would temporarily assume Mariaca’s duties.

The arrests come as Bolivian President Rodrigo Paz seeks closer security cooperation with the United States after taking office in November 2025. Paz’s government has moved to strengthen ties with Washington following years of strained relations under Bolivia’s previous socialist governments.

The U.S. government has backed Bolivia’s crackdown. Secretary of State Marco Rubio described the arrests as actions against drug trafficking, corruption and transnational organized crime.

Bolivian authorities also raided prosecutor’s offices in Santa Cruz, La Paz and Sucre. Officials at the prosecutor’s office initially denounced Mariaca’s detention as an illegal “abduction,” while his lawyer said he would cooperate with investigators.
