Bolsonaro has been detained after authorities concluded he posed a serious risk of fleeing while under house arrest.
The ex-president was sentenced of plotting a military coup in last fall and sentenced more than over two decades in jail, but he remained under home detention pending legal challenges.
Top Judicial Official Alexandre de Moraes said the decision to arrest the septuagenarian politician was a safety action after recent developments came to light.
This encompassed seeking to disable his tracking device and a call for a demonstration that could enable a chance to flee".
Judicial Records Show Flight Fears
In a filing authorising the arrest, the magistrate said intelligence from the facility tracking the former president's confinement suggested the ex-president's aim to disable the tracking monitor to secure accomplishment in his flight.
This, it said, would be assisted by the confusion caused by the gathering called by his offspring.
His son, Flávio, who holds office as a senator, called for a gathering of his supporters near Bolsonaro's home to take place on the weekend.
The senator wrote on online platforms on last Friday: Will you battle for your nation, or watch it all from your smartphone there on your sofa? I call on you to struggle with us."
He said the gathering would be so supporters could seek divine intervention for his well-being and for the return of democracy in our country."
Embassy Asylum Concerns
Part of the magistrate's decision was the chance of Bolsonaro's move to embassies near the home, considering that the inquiries revealed a history of organizing to seek refuge through a consular facility", a declaration said.
The court filing emphasizes that the US embassy in the federal district, Brazil's capital, is situated around 13km from Bolsonaro's home.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow populist conservative American leader Donald Trump, prompting him to impose a fifty percent tax on goods coming from Brazil.
He is being held in a Federal Police station in the capital and will experience a imprisonment assessment on the following day.
Recent Judicial Appeals
It was only on last Friday that the his legal team asked the High Court to authorize him to complete his entire prison term under domestic detention, with digital surveillance.
They also requested that the former president be allowed to leave his home for medical care, saying he needed regular treatment for pulmonary infections and other illnesses.
Details of Guilty Verdict
He was found guilty of orchestrating a plot aimed at keeping him in power after he failed to win the national vote to his ideological adversary, President Lula.
Top judicial officials said that he was aware of a plot which included plans to kill the current president and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute the presiding judge - the Supreme Court justice who has been managing the former president's case.
The plot was prevented because it couldn't obtain the endorsement of the army and air force commanders. Lula was inaugurated without problem on 1 January 2023.
But a following week, on 8 January, numerous his followers stormed and vandalised government buildings in the capital, the capital city.
The police intervened and around approximately 1,500 persons were detained.
The judges found that the demonstrators had been incited by Bolsonaro whose strategy, they said, was for the national armed forces to take action, restore order and bring him back to power.
At the time, his attorneys called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from running for public office until the year 2060 - eight years later after the end of his sentence.
The former president called the legal proceedings a political persecution and said it was aimed at blocking him running in the 2026 presidential election.
