The former Brazilian leader has been taken into custody after authorities determined he posed a concrete flight risk while under domestic detention.
The ex-president was convicted of planning a government overthrow in September and given more than a 27-year term in incarceration, but he remained under house arrest pending legal challenges.
High Court Judge Alexandre de Moraes said the action to imprison the 70-year-old politician was a preventative measure after recent developments emerged.
This included seeking to disable his electronic bracelet and a summons to a demonstration that could enable a potential flight.
Court Filing Details Flight Fears
In a document approving the arrest, the judge said information from the unit overseeing his home detention suggested the one-time head of state's plan to remove the electronic ankle bracelet to ensure success in his flight.
This, it said, would be assisted by the confusion caused by the gathering called by his son.
His son, Flávio Bolsonaro, who holds office as a congressional representative, called for a gathering of his followers near Bolsonaro's home to take place on Saturday night.
His son wrote on digital networks on Friday: "Are you going to fight for your country, or see it all from your smartphone there on your settee? I call on you to struggle with us."
He said the gathering would be so backers could "pray for his physical condition and for the restoration of democratic rule in our country."
Foreign Shelter Risks
Part of Justice Moraes's determination was the potential of his transfer to diplomatic missions near the dwelling, considering that the inquiries revealed a record of organizing to seek refuge through a embassy office", a declaration said.
The legal document emphasizes that the United States embassy in the federal district, Brasilia, is positioned around 8 miles from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have generated frustration from fellow right-wing populist American leader Donald Trump, prompting him to enact a fifty percent tax on goods coming from Brazil.
He is being kept in a Federal Police station in Brasilia and will undergo a imprisonment assessment on the following day.
Recent Legal Requests
It was only on Friday that the ex-leader's attorneys asked the High Court to authorize him to serve his whole jail sentence under house arrest, with digital surveillance.
They also requested that the former president be permitted to depart his residence for medical care, saying he demanded ongoing care for respiratory ailments and other health problems.
Context of Sentencing
He was convicted of heading a plot aimed at keeping him in power after he lost the 2022 election to his left-wing rival, Lula.
Top judicial officials said that he had knowledge of a plot which encompassed plans to assassinate his opponent and his vice-presidential running mate, Alckmin, and to arrest and execute the presiding judge - the High Court judge who has been presiding over his judicial proceedings.
The scheme was stopped because it couldn't obtain the support of the military leaders. His successor was inaugurated without problem on the first day of 2023.
But a following week, on 8 January, thousands of his followers invaded and destroyed official structures in the national capital, the capital city.
The security forces took action and around approximately 1,500 persons were arrested.
The judges found that the demonstrators had been provoked by him whose scheme, they said, was for the country's army to intervene, bring back stability and reinstate his authority.
At the period, the legal team called the decades-long sentence unreasonably severe".
He was also barred from campaigning for office until twenty-sixty - eight years later after the completion of his term.
The one-time head of state called the trial a political persecution and said it was designed to prevent him running in the 2026 national vote.
