Bolsonaro has been arrested after authorities found he posed a serious risk of fleeing while under home confinement.
The ex-president was convicted of plotting a armed takeover in the ninth month and handed more than a 27-year term in jail, but he was staying under home detention pending legal challenges.
High Court Judge the presiding justice said the move to detain the septuagenarian politician was a precautionary step after "new facts" emerged.
This encompassed trying to remove his electronic bracelet and a call for a public vigil that could "allow for a possible escape.
Court Filing Details Flight Fears
In a paperwork permitting the detention, the magistrate said intelligence from the unit overseeing the former president's confinement suggested the former leader's plan to remove the electronic ankle bracelet to secure accomplishment in his flight.
This, it said, would be made easier by the confusion caused by the protest called by his son.
His child, Flávio Bolsonaro, who serves as a senator, called for a meeting of his supporters near his father's house to take place on Saturday night.
His son wrote on social media on the previous day: Will you battle for your nation, or observe everything from your phone there on your settee? I urge you to struggle with us."
He said the gathering would be so supporters could offer prayers for his health and for the restoration of democratic rule in our country."
Embassy Asylum Concerns
Part of Justice Moraes's ruling was the possibility of the former president's move to diplomatic missions near the residence, considering that the probes revealed a background of arranging to seek refuge through a consular facility", a declaration said.
The legal document emphasizes that the United States embassy in the capital, Brazil's capital, is positioned around 8 miles from Bolsonaro's home.
International Reactions
His judicial problems have provoked anger from fellow right-wing populist United States President Donald Trump, causing him to implement a fifty percent tax on Brazilian product imports.
The former president is being kept in a federal law enforcement building in Brasilia and will experience a custody hearing on the following day.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the Supreme Court to allow him to fulfill his full incarceration period under home confinement, with tracking devices.
They also requested that Bolsonaro be authorized to exit his dwelling for healthcare, saying he required regular treatment for pulmonary infections and other illnesses.
Background on Conviction
The former president was found guilty of leading a scheme aimed at retaining his authority after he was defeated in the national vote to his ideological adversary, Lula.
Supreme Court justices said that he knew of a plan which included plans to kill his opponent and his VP candidate, Alckmin, and to detain and kill Alexandre de Moraes - the High Court judge who has been overseeing his judicial proceedings.
The conspiracy was prevented because it couldn't obtain the backing of the armed forces officials. The current president was took office without problem on 1 January 2023.
But a seven days after, on January 8th, thousands of his backers invaded and destroyed official structures in the federal district, the capital city.
The police intervened and around fifteen hundred individuals were taken into custody.
The magistrates found that the demonstrators had been provoked by the former president whose strategy, they said, was for the national armed forces to step in, bring back stability and reinstate his authority.
At the period, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also prohibited from seeking elected position until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the court case a political persecution and said it was intended to stop him running in the next presidential race.
