Bolsonaro has been taken into custody after authorities determined he posed a concrete flight risk while under house arrest.
The one-time leader was found guilty of planning a armed takeover in last fall and handed more than over two decades in incarceration, but he continued under home detention pending appeals.
Top Judicial Official Alexandre de Moraes said the move to detain the septuagenarian politician was a precautionary step after recent developments were revealed.
This encompassed attempting to break his ankle monitor and a call for a demonstration that could facilitate a possible escape.
Judicial Records Show Escape Risks
In a paperwork permitting the detention, the judge said information from the facility tracking the former president's confinement suggested the ex-president's aim to disable the surveillance device to guarantee victory in his escape.
This, it said, would be assisted by the chaos caused by the demonstration called by his child.
His offspring, Flávio Bolsonaro, who serves as a legislator, called for a assembly of his supporters near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on online platforms on last Friday: Do you plan to struggle for your nation, or observe everything from your mobile device there on your settee? I call on you to struggle with us."
He said the gathering would be so followers could "pray for his well-being and for the restoration of democratic rule in our nation."
Embassy Asylum Concerns
Part of the judge's ruling was the chance of his move to diplomatic missions near the home, considering that the probes revealed a background of arranging to seek refuge through a embassy office", a announcement said.
The legal document emphasizes that the American diplomatic mission in the capital, Brazil's capital, is situated around approximately 13 kilometers from Bolsonaro's home.
Worldwide Consequences
Bolsonaro's legal woes have provoked anger from fellow populist conservative United States President Donald Trump, prompting him to implement a half-rate duty on imports of Brazilian goods.
He is being held in a federal law enforcement building in the capital and will have a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the Top Court to authorize him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that Bolsonaro be allowed to exit his dwelling for healthcare, saying he demanded regular treatment for pulmonary infections and other ailments.
Context of Sentencing
The former president was determined responsible of heading a plot aimed at keeping him in power after he was defeated in the presidential race to his ideological adversary, Lula.
Top judicial officials said that he had knowledge of a plan which involved plans to kill Lula and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The plot was stopped because it failed to get the endorsement of the army and air force commanders. His successor was inaugurated without incident on January 1st, 2023.
But a following week, on the eighth of January, many Bolsonaro supporters attacked and damaged official structures in the federal district, Brazil's capital.
The security forces intervened and around 1,500 people were arrested.
The judges found that the demonstrators had been provoked by him whose plan, they said, was for the country's army to intervene, reestablish control and bring him back to power.
At the moment, the legal team called the 27 years and three months sentence extremely harsh.
He was also banned from running for public office until the year 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the trial a targeted investigation" and said it was designed to prevent him participating in the 2026 national vote.
