The former Brazilian leader has been detained after authorities concluded he posed a concrete flight risk while under house arrest.
The ex-president was sentenced of plotting a armed takeover in last fall and sentenced more than a 27-year term in jail, but he continued under house arrest pending legal challenges.
Top Judicial Official the presiding justice said the move to detain the septuagenarian politician was a safety action after "new facts" came to light.
This involved attempting to break his ankle monitor and a call for a demonstration that could facilitate a potential flight.
Judicial Records Show Escape Concerns
In a filing authorising the detention, the judge said intelligence from the facility tracking his home detention suggested the ex-president's aim to disable the tracking monitor to guarantee victory in his escape.
This, it said, would be made easier by the disorder caused by the demonstration called by his offspring.
His child, his son Flávio, who serves as a legislator, called for a meeting of his supporters near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on social media on Friday: Will you battle for your homeland, or observe everything from your mobile device there on your settee? I invite you to struggle with us."
He said the vigil would be so backers could seek divine intervention for his physical condition and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of Justice Moraes's decision was the chance of the former president's move to diplomatic missions near the dwelling, considering that the inquiries revealed a record of organizing to seek refuge through a diplomatic representation", a statement said.
The judicial paperwork highlights that the US embassy in the federal district, Brazil's capital, is located around 13km from Bolsonaro's home.
International Reactions
Bolsonaro's legal woes have generated frustration from fellow right-wing populist United States President President Trump, causing him to enact a half-rate duty on Brazilian product imports.
He is being kept in a national police facility in the capital and will undergo a imprisonment assessment on Sunday.
Recent Judicial Appeals
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to allow him to complete his entire prison term under house arrest, with electronic monitoring.
They also requested that he be permitted to exit his dwelling for healthcare, saying he required ongoing care for pulmonary infections and other illnesses.
Context of Sentencing
Bolsonaro was convicted of orchestrating a conspiracy aimed at keeping him in power after he failed to win the national vote to his political opponent, Lula.
High Court judges said that he was aware of a scheme which involved plans to kill the current president and his vice-presidential running mate, Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been managing Bolsonaro's trial.
The plot was stopped because it didn't receive the endorsement of the army and air force commanders. Lula was sworn in without incident on 1 January 2023.
But a following week, on 8 January, numerous his followers attacked and damaged government buildings in the federal district, the capital city.
The law enforcement intervened and around 1,500 people were detained.
The magistrates found that the protesters had been incited by him whose strategy, they said, was for the national armed forces to intervene, reestablish control and return him to office.
At the period, his attorneys called the over 27-year sentence "absurdly excessive.
He was also barred from seeking elected position until 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the legal proceedings a targeted investigation" and said it was intended to stop him running in the 2026 national vote.
