The arrest comes after an attack on activist Nadia Beller, who says she was targeted for her opposition to conservative reforms and corruption.

Bolivia has arrested a prominent adviser to several right-wing political leaders in Latin America on suspicion of plotting a murder.

Fernando Cerimedo was arrested on Tuesday following an attack on lawyer and political activist Nadia Beller. The consultant has worked on political campaigns for Argentina’s President Javier Milei, former Brazilian President Jair Bolsonaro, and Bolivia’s President Rodrigo Paz.

The Argentinian national was arrested in Bolivia at an airport, trying to travel to his home country.

Security videos captured Beller standing in front of a hotel in Santa Cruz when two men dressed as delivery drivers walked up the stairs, shot her from close range, took some of her belongings, and left her behind as she lay on the ground.

Beller, who was four weeks pregnant, believes she was targeted for her opposition to a pack of unconstitutional laws under Decree 5503, which were being prepared by Cerimedo and the government, and for witnessing high-level corruption.

Decree 5503 introduces radical economic reforms, such as eliminating state fuel subsidies, that target policies put in place under Bolivia’s former socialist government.

Beller is also understood to have had a romantic relationship with Cerimedo. She admitted to her relationship with him in a video appearance from her hospital bed, and highlighted Cerimedo’s significant political influence.

She said she decided to speak out as she believes that “until I speak directly to the Bolivian people, they are going to finish what they attempted to do. They are going to end up taking my life”.

Bolivian Vice President Edmand Lara said the attack “threatens life, democracy, and freedom of expression” in a news conference where he called for an impartial investigation “without any kind of favoritism”.
