Bolsonaro has been detained after authorities found he posed a concrete flight risk while under home confinement.
The former head of state was convicted of planning a armed takeover in last fall and given more than 27 years in prison, but he was staying under house arrest pending legal challenges.
Brazilian Supreme Court Justice the presiding justice said the move to detain the septuagenarian politician was a safety action after fresh information were revealed.
This involved seeking to disable his ankle monitor and a summons to a supporters' gathering that could facilitate a chance to flee".
Judicial Records Show Escape Risks
In a document approving the custody, the judge said intelligence from the centre monitoring his home detention suggested the former leader's aim to disable the electronic ankle bracelet to guarantee victory in his escape.
This, it said, would be made easier by the chaos caused by the protest called by his son.
His child, Flávio Bolsonaro, who works as a legislator, called for a assembly of his supporters near his father's house to take place on the weekend.
Flávio Bolsonaro wrote on social media on last Friday: Do you plan to struggle for your country, or observe everything from your smartphone there on your couch? I invite you to fight with us."
He said the vigil would be so supporters could seek divine intervention for his health and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of the former president's move to foreign missions near the dwelling, considering that the inquiries revealed a background of organizing to seek refuge through a consular facility", a announcement said.
The court filing underscores that the United States embassy in the capital, the capital city, is situated around 8 miles from his dwelling.
International Reactions
The former president's legal troubles have provoked anger from fellow populist conservative American leader President Trump, prompting him to implement a half-rate duty on Brazilian product imports.
Bolsonaro is being held in a federal law enforcement building in Brasilia and will undergo a custody hearing on Sunday.
Recent Judicial Appeals
It was only on Friday that the former president's lawyers asked the Top Court to authorize him to fulfill his full incarceration period under domestic detention, with digital surveillance.
They also asked that the former president be permitted to leave his home for medical care, saying he needed frequent medical attention for pulmonary infections and other illnesses.
Background on Conviction
Bolsonaro was convicted of orchestrating a conspiracy aimed at keeping him in power after he was defeated in the national vote to his ideological adversary, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a plot which encompassed plans to murder Lula and his running partner, Geraldo Alckmin, and to arrest and execute Justice Moraes - the Supreme Court justice who has been managing Bolsonaro's trial.
The plot was stopped because it failed to get the backing of the armed forces officials. His successor was took office without issue on 1 January 2023.
But a following week, on January 8th, many Bolsonaro supporters attacked and damaged public facilities in the federal district, Brazil's capital.
The security forces stepped in and around 1,500 people were taken into custody.
The judges found that the rioters had been provoked by him whose strategy, they said, was for the country's army to step in, restore order and reinstate his authority.
At the moment, the legal team called the over 27-year sentence "absurdly excessive.
He was also barred from campaigning for office until 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the court case a targeted investigation" and said it was intended to stop him running in the 2026 presidential election.
