Machado posted on X that Juan Pablo Guanipa, a key ally, was seized by heavily armed men wearing civilian clothes in the Los Chorros district of the capital.

She demanded his immediate release.

Alfredo Romero, president of the group Foro Penal, said 35 political prisoners were freed on Sunday, including Guanipa, who was first arrested in May.

Reuters reported Venezuelan authorities were seeking judicial approval to put Guanipa under house arrest.

The nation’s Public Ministry alleged he violated his release terms but gave no further details and did not confirm if he had been re-arrested.

Guanipa’s Primero Justicia party said on X he was forced into a silver Toyota Corolla during the incident.

The party wrote, “We hold , Jorge Rodríguez, and Diosdado Cabello responsible for any harm to Juan Pablo’s life.” It called on the international community to demand the immediate release of Juan Pablo Guanipa and an immediate, unconditional end to opposition persecution.

The U.S. State Department did not immediately reply to Digital’s request for comment.

Rodríguez has served as Venezuela’s interim president since the U.S. capture of and his wife Cilia Flores earlier this year.

In late January, President said Venezuela was freeing political prisoners at a “rapid rate,” calling it a “powerful humanitarian gesture” by the country’s leadership.

An estimated 687 political prisoners remain detained in Venezuela as of Feb. 2, according to Foro Penal.
