Bolivian President Luis Arce on Thursday denied any involvement or prior knowledge of a failed coup attempt led by the country's former top military commander who alleged the president had asked him to do something to boost his popularity, Ednews reports citing Reuters.

"We were never informed about his intentions," Arce told reporters during a press conference at government headquarters. "We were surprised."

The mobilization of military units on Wednesday saw Juan Jose Zuniga gather troops in the main square of capital La Paz, ramming a palace door with an armored vehicle to allow soldiers to rush into the building.

Zuniga, who was soon arrested, told reporters that Arce had asked him to help boost popularity.

Local news agency Fides reported Zuniga told police Arce had three days earlier authorized him to mobilize the armored vehicles "with the objective of controlling the situation of conflicts in the country."

Earlier on Thursday, Interior Minister Eduardo del Castillo said in an interview that Arce had received reports of "destabilization attempts," though the government did not know more at the time.

Arce said Zuniga "acted on his own accord," and upon learning of what was happening, the leader called ex-President Evo Morales, his former ally turned political rival, to warn him.

"It was clear that they were coming for me," Arce said, "and after they were going for Evo Morales."

Zuniga was arrested along with former Navy commander Juan Arnez Salvador, Del Castillo said. He later said 17 people had been detained so far, but there were "many more who had participated."
