Bolsonaro has been arrested after authorities found he posed a concrete flight risk while under domestic detention.
The one-time leader was found guilty of planning a armed takeover in September and handed more than a 27-year term in prison, but he was staying under home detention pending legal challenges.
High Court Judge the presiding justice said the move to detain the 70-year-old politician was a preventative measure after fresh information came to light.
This encompassed attempting to break his electronic bracelet and a call for a demonstration that could "allow for a potential flight.
Judicial Records Show Escape Risks
In a filing authorising the custody, the magistrate said data from the facility tracking his home detention suggested the ex-president's plan to remove the tracking monitor to guarantee victory in his escape.
This, it said, would be assisted by the chaos caused by the demonstration called by his son.
His child, Flávio, who serves as a legislator, called for a gathering of his backers near his father's house to take place on Saturday night.
His son wrote on digital networks on last Friday: "Are you going to fight for your homeland, or watch it all from your mobile device there on your settee? I urge you to fight with us."
He said the gathering would be so followers could offer prayers for his physical condition and for the return of democracy in our country."
Foreign Shelter Risks
Part of Justice Moraes's decision was the chance of Bolsonaro's "relocation to embassies near the residence, considering that the inquiries revealed a background of arranging to request asylum through a consular facility", a statement said.
The court filing emphasizes that the United States embassy in the capital, the capital city, is situated around approximately 13 kilometers from his dwelling.
Global Responses
The former president's legal troubles have generated frustration from fellow conservative nationalist US President President Trump, leading him to enact a fifty percent tax on goods coming from Brazil.
He is being detained in a Federal Police station in the capital and will experience a detention review on the following day.
Recent Legal Requests
It was only on last Friday that the his legal team asked the High Court to allow him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also asked that he be allowed to depart his residence for medical treatment, saying he needed ongoing care for lung conditions and other ailments.
Details of Guilty Verdict
He was convicted of leading a scheme aimed at maintaining his control after he was defeated in the national vote to his political opponent, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plan which encompassed plans to murder the current president and his vice-presidential running mate, Alckmin, and to arrest and execute Alexandre de Moraes - the top judicial official who has been presiding over Bolsonaro's trial.
The scheme was thwarted because it couldn't obtain the support of the army and air force commanders. Lula was inaugurated without incident on 1 January 2023.
But a seven days after, on 8 January, many his backers invaded and destroyed public facilities in the capital, Brasília.
The police took action and around fifteen hundred individuals were taken into custody.
The magistrates found that the protesters had been provoked by the former president whose scheme, they said, was for the country's army to intervene, bring back stability and reinstate his authority.
At the moment, his attorneys called the decades-long sentence unreasonably severe".
He was also prohibited from running for public office until the year 2060 - a decade minus two years after the end of his sentence.
The ex-leader called the court case a targeted investigation" and said it was aimed at blocking him participating in the 2026 national vote.
