Bolsonaro has been detained after authorities determined he posed a serious risk of fleeing while under house arrest.
The one-time leader was sentenced of orchestrating a armed takeover in the ninth month and sentenced more than a 27-year term in incarceration, but he continued under house arrest pending appeals.
Top Judicial Official Justice Moraes said the action to imprison the 70-year-old politician was a precautionary step after fresh information emerged.
This included attempting to break his ankle monitor and a summons to a public vigil that could "allow for a possible escape.
Court Filing Details Escape Risks
In a document approving the custody, Justice Moraes said intelligence from the facility tracking his home detention suggested the ex-president's aim to disable the electronic ankle bracelet to guarantee victory in his flight.
This, it said, would be assisted by the confusion caused by the gathering called by his child.
His son, Flávio, who serves as a legislator, called for a assembly of his followers near Bolsonaro's home to take place on the weekend.
His son wrote on digital networks on the previous day: "Are you going to fight for your homeland, or observe everything from your smartphone there on your settee? I invite you to struggle with us."
He said the gathering would be so supporters could offer prayers for his physical condition and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the chance of the former president's transfer to embassies near the residence, considering that the investigations revealed a record of arranging to seek refuge through a embassy office", a announcement said.
The court filing emphasizes that the United States embassy in the capital, Brasilia, is located around approximately 13 kilometers from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have provoked anger from fellow right-wing populist United States President Trump, prompting him to enact a 50% tariff on Brazilian product imports.
He is being kept in a Federal Police station in the capital and will have a detention review on the following day.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to permit him to serve his whole jail sentence under home confinement, with tracking devices.
They also asked that he be allowed to depart his residence for medical treatment, saying he needed regular treatment for lung conditions and other illnesses.
Details of Guilty Verdict
The former president was found guilty of orchestrating a plot aimed at keeping him in power after he was defeated in the 2022 election to his political opponent, President Lula.
Top judicial officials said that he was aware of a plan which involved plans to assassinate the current president and his vice-presidential running mate, Alckmin, and to arrest and execute Alexandre de Moraes - the High Court judge who has been overseeing Bolsonaro's trial.
The plot was thwarted because it failed to get the support of the army and air force commanders. His successor was inaugurated without problem on January 1st, 2023.
But a seven days after, on January 8th, many Bolsonaro supporters stormed and vandalised public facilities in the national capital, the capital city.
The security forces took action and around approximately 1,500 persons were taken into custody.
The magistrates found that the demonstrators had been incited by the former president whose plan, they said, was for the national armed forces to take action, bring back stability and return him to office.
At the moment, Bolsonaro's lawyers called the decades-long sentence "absurdly excessive.
He was also banned from running for public office until the year 2060 - eight years later after the end of his sentence.
The one-time head of state called the court case a "witch hunt and said it was intended to stop him competing in the 2026 presidential election.
