LA PAZ, Bolivia (AP) — Bolivian officials announced Friday they had arrested four more military officers in connection with Wednesday’s thwarted coup against the government of President Luis Arce, raising to 21 the number of detainees allegedly linked to a rogue general’s mutiny attempt.

In a press conference, senior Cabinet member Eduardo del Castillo said those arrested include the driver of a tank that repeatedly rammed into the doors of the government headquarters and a former infantry captain accused of giving orders to soldiers who took over the capital’s central Plaza Murillo.

“These people commanded the destruction of Bolivian heritage,” del Castillo said.

The coup attempt was led by Juan José Zuñiga, who until his public sacking and arrest Wednesday was the commanding general of the army. Zuñiga has alleged, without providing evidence, that Arce ordered him to carry out the rebellion in a ruse to boost his flagging popularity as he struggles to manage a spiraling economy and bubbling public discontent.

Arce on Thursday night vigorously denied accusations that he had carried out a “self-coup” to garner political support.
