Bolivia's ex-president Jeanine Anez said that she was being abused in prison amid her pre-trial detention.

Anez was arrested on a charge of leading a coup d'etat against her socialist predecessor Evo Morales.

Morales exiled to Argentina after a failed attempt to extend his stay as the country's president by seeking a fourth term. He led Bolivia for about 14 years before leaving office under pressure from the military, according to an NPR report.

He then returned to the country last November, describing the event as one of the most important days of his life.

Meanwhile, Anez's pre-trial detention was extended two months as a prison official announced that the former president will receive medical care at La Paz penitentiary, where she is being jailed.

Abuse in Prison

Anez alleged the abuse in a seven-page letter that was posted on Twitter. She said that there abusive actions by the police and the state, further claiming that the authorities were refusing to provide her proper medical treatment, according to a DW report.

Anez wrote that she does not trust the government's doctors, adding that she wanted to be treated by independent medics rather than those already serving in prison.

"They're part of the system of abuse and repression and have shown they're prepared to risk my life, injecting me with high-risk medication without precautions or previous studies, with the only aim of keeping me in their cells," Anez was quoted in a report.

Her lawyer, Ariel Coronado, said that the state had approved of having a cardiologist visit the former president in prison. Coronado added that Anez was depressed.

Anez further said that this is a fight for democracy and they will keep on fighting until the end, according to a Reuters report.

A government spokesman did not respond to a request for comment on the former president's abuse allegations; same for police spokesman.

Anez was transferred to the Miraflores Women's Penitentiary from another detention center in the Bolivian capital.

Prisons chief Juan Carlos Limpias said that at Miraflores, they have everything they need to preserve her health, according to an AFP News report.

Coup d'etat Case

Anez rose to power in 2019 after Morales and senior MAS allies resigned after protests over his controversial reelection erupted in the country.

Anez was sworn by Congress as the interim president despite the lack of a quorum.

Prosecutors claimed that Anez and her allies threatened those before her in the line of succession to step down and allow her to become interim president.

During her administration, Morales was alleged of terrorism, and some of his government allies were detained. At least 33 people were killed in the violence after the 2019 presidential election.

Out of that death toll, 30 were killed after Anez took office.

Several days before the coup, right-wing people headed violent rampages against Indigenous Bolivians and MAS members. They also burned the houses of Morales, his sister, and other MAS politicians, according to a CovertAction Magazine report.
