The former Brazilian leader has been arrested after authorities determined he posed a serious risk of fleeing while under domestic detention.
The ex-president was sentenced of orchestrating a armed takeover in the ninth month and sentenced more than over two decades in incarceration, but he continued under home detention pending court reviews.
Top Judicial Official Justice Moraes said the move to detain the elderly politician was a precautionary step after "new facts" came to light.
This involved seeking to disable his tracking device and a call for a public vigil that could "allow for a possible escape.
Judicial Records Show Flight Fears
In a filing authorising the custody, the magistrate said intelligence from the unit overseeing Bolsonaro's house arrest suggested the one-time head of state's aim to disable the tracking monitor to guarantee victory in his escape.
This, it said, would be assisted by the confusion caused by the protest called by his offspring.
His son, his son Flávio, who works as a legislator, called for a gathering of his backers near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on social media on the previous day: Do you plan to struggle for your country, or see it all from your smartphone there on your sofa? I invite you to battle with us."
He said the vigil would be so followers could "pray for his physical condition and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of the magistrate's determination was the chance of Bolsonaro's "relocation to embassies near the home, considering that the probes revealed a record of arranging to request asylum through a diplomatic representation", a announcement said.
The court filing underscores that the US embassy in the national capital, Brasilia, is positioned around 13km from Bolsonaro's home.
International Reactions
Bolsonaro's legal woes have provoked anger from fellow populist conservative American leader Trump, causing him to implement a 50% tariff on goods coming from Brazil.
Bolsonaro is being kept in a national police facility in Brazil's capital city and will have a imprisonment assessment on the next day.
Latest Court Petitions
It was only on the previous day that the former president's lawyers asked the Supreme Court to allow him to complete his entire prison term under house arrest, with digital surveillance.
They also petitioned that he be permitted to depart his residence for medical care, saying he required ongoing care for lung conditions and other illnesses.
Details of Guilty Verdict
The former president was found guilty of heading a conspiracy aimed at maintaining his control after he was defeated in the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plot which encompassed plans to kill his opponent and his vice-presidential running mate, his vice-presidential candidate, and to imprison and murder Alexandre de Moraes - the High Court judge who has been presiding over his judicial proceedings.
The plot was thwarted because it failed to get the support of the military leaders. The current president was inaugurated without problem on the first day of 2023.
But a following week, on January 8th, thousands of his followers attacked and damaged public facilities in the capital, the capital city.
The police stepped in and around 1,500 people were arrested.
The judges found that the demonstrators had been incited by the former president whose plan, they said, was for the national armed forces to intervene, restore order and reinstate his authority.
At the period, Bolsonaro's lawyers called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from seeking elected position until twenty-sixty - eight years after the end of his sentence.
The former president called the trial a targeted investigation" and said it was intended to stop him participating in the 2026 national vote.
