The former Brazilian leader has been taken into custody after authorities determined he posed a serious risk of fleeing while under house arrest.
The former head of state was sentenced of orchestrating a armed takeover in September and sentenced more than 27 years in prison, but he remained under home detention pending court reviews.
High Court Judge Alexandre de Moraes said the move to detain the septuagenarian politician was a safety action after fresh information were revealed.
This involved attempting to break his electronic bracelet and a call for a supporters' gathering that could "allow for a chance to flee".
Legal Document Reveals Flight Fears
In a filing authorising the detention, the magistrate said data from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's aim to disable the tracking monitor to guarantee victory in his getaway".
This, it said, would be "facilitated by the chaos caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who holds office as a senator, called for a assembly of his backers near the former president's residence to take place on the weekend.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your country, or watch it all from your mobile device there on your settee? I invite you to fight with us."
He said the demonstration would be so backers could seek divine intervention for his physical condition and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the judge's decision was the chance of the former president's move to embassies near the home, considering that the inquiries revealed a history of organizing to request asylum through a embassy office", a announcement said.
The judicial paperwork underscores that the United States embassy in the national capital, the capital city, is positioned around 8 miles from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have drawn the ire of fellow populist conservative US President Donald Trump, leading him to impose a 50% tariff on goods coming from Brazil.
He is being kept in a federal law enforcement building in the capital and will experience a imprisonment assessment on the next day.
Recent Legal Requests
It was only on last Friday that the ex-leader's attorneys asked the Supreme Court to allow him to fulfill his full incarceration period under home confinement, with tracking devices.
They also requested that he be allowed to depart his residence for healthcare, saying he needed frequent medical attention for lung conditions and other illnesses.
Context of Sentencing
He was determined responsible of heading a scheme aimed at retaining his authority after he was defeated in the presidential race to his political opponent, Lula.
Supreme Court justices said that he had knowledge of a plot which encompassed plans to assassinate his opponent and his running partner, his vice-presidential candidate, and to detain and kill Alexandre de Moraes - the High Court judge who has been managing his judicial proceedings.
The conspiracy was thwarted because it failed to get the support of the army and air force commanders. Lula was took office without problem on 1 January 2023.
But a week later, on January 8th, thousands of his backers attacked and damaged government buildings in the capital, the capital city.
The police intervened and around 1,500 people were detained.
The judges found that the protesters had been encouraged by the former president whose scheme, they said, was for the country's army to take action, bring back stability and reinstate his authority.
At the moment, the legal team called the over 27-year sentence extremely harsh.
He was also barred from campaigning for office until 2060 - eight years later after the end of his sentence.
The one-time head of state called the legal proceedings a targeted investigation" and said it was intended to stop him running in the next presidential race.
