Bolsonaro has been taken into custody after authorities concluded he posed a concrete flight risk while under home confinement.
The former head of state was convicted of plotting a government overthrow in September and sentenced more than 27 years in jail, but he remained under house arrest pending court reviews.
Top Judicial Official Alexandre de Moraes said the decision to arrest the 70-year-old politician was a preventative measure after recent developments came to light.
This included attempting to break his ankle monitor and a invitation to a demonstration that could enable a chance to flee".
Court Filing Details Flight Fears
In a paperwork permitting the arrest, the magistrate said intelligence from the facility tracking his home detention suggested the one-time head of state's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be assisted by the confusion caused by the protest called by his child.
His son, his son Flávio, who holds office as a congressional representative, called for a assembly of his followers near the former president's residence to take place on Saturday evening.
His son wrote on digital networks on the previous day: Do you plan to struggle for your homeland, or see it all from your phone there on your settee? I invite you to struggle with us."
He said the demonstration would be so backers could "pray for his well-being and for the restoration of democratic rule in our nation."
Embassy Asylum Concerns
Part of Justice Moraes's ruling was the chance of the former president's move to foreign missions near the dwelling, considering that the investigations revealed a background of arranging to request asylum through a embassy office", a declaration said.
The legal document underscores that the United States embassy in the national capital, the capital city, is positioned around 13km from Bolsonaro's home.
Worldwide Consequences
Bolsonaro's legal woes have generated frustration from fellow right-wing populist United States President Donald Trump, prompting him to impose a 50% tariff on imports of Brazilian goods.
The former president is being kept in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on the following day.
Recent Legal Requests
It was only on Friday that the former president's lawyers asked the High Court to authorize him to fulfill his full incarceration period under domestic detention, with electronic monitoring.
They also asked that the former president be authorized to exit his dwelling for healthcare, saying he required frequent medical attention for lung conditions and other health problems.
Details of Guilty Verdict
He was determined responsible of heading a scheme aimed at keeping him in power after he lost the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
Supreme Court justices said that he knew of a plot which encompassed plans to murder the current president and his running partner, his vice-presidential candidate, and to detain and kill the presiding judge - the High Court judge who has been presiding over the former president's case.
The conspiracy was prevented because it didn't receive the backing of the army and air force commanders. Lula was sworn in without issue on January 1st, 2023.
But a seven days after, on January 8th, many his backers invaded and destroyed government buildings in the federal district, Brasília.
The police intervened and around fifteen hundred individuals were detained.
The justices found that the demonstrators had been incited by Bolsonaro whose plan, they said, was for the country's army to step in, reestablish control and return him to office.
At the moment, the legal team called the 27 years and three months sentence unreasonably severe".
He was also banned from seeking elected position until the year 2060 - eight years after the completion of his term.
The former president called the legal proceedings a "witch hunt and said it was intended to stop him running in the next presidential race.
