Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under house arrest.
The one-time leader was sentenced of planning a armed takeover in the ninth month and sentenced more than over two decades in incarceration, but he continued under confinement pending legal challenges.
Brazilian Supreme Court Justice Justice Moraes said the action to imprison the septuagenarian politician was a precautionary step after recent developments were revealed.
This encompassed trying to remove his tracking device and a invitation to a demonstration that could facilitate a possible escape.
Legal Document Reveals Flight Fears
In a paperwork permitting the detention, the magistrate said intelligence from the unit overseeing Bolsonaro's house arrest suggested the ex-president's aim to disable the surveillance device to ensure success in his escape.
This, it said, would be made easier by the chaos caused by the demonstration called by his son.
His offspring, Flávio Bolsonaro, who works as a senator, called for a gathering of his supporters near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on Friday: "Are you going to fight for your country, or observe everything from your mobile device there on your couch? I invite you to struggle with us."
He said the demonstration would be so backers could "pray for his physical condition and for the reestablishment of democratic governance in our nation."
Embassy Asylum Concerns
Part of the judge's decision was the chance of Bolsonaro's "relocation to diplomatic missions near the home, considering that the investigations revealed a background of planning to request asylum through a consular facility", a announcement said.
The court filing underscores that the American diplomatic mission in the federal district, Brasilia, is situated around 8 miles from the former president's residence.
International Reactions
His judicial problems have generated frustration from fellow right-wing populist American leader President Trump, prompting him to impose a half-rate duty on Brazilian product imports.
He is being kept in a federal law enforcement building in Brasilia and will experience a custody hearing on the next day.
Recent Judicial Appeals
It was only on Friday that the former president's lawyers asked the Supreme Court to permit him to complete his entire prison term under home confinement, with digital surveillance.
They also requested that the former president be allowed to depart his residence for medical treatment, saying he demanded ongoing care for lung conditions and other illnesses.
Details of Guilty Verdict
Bolsonaro was determined responsible of orchestrating a plot aimed at retaining his authority after he failed to win the presidential race to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he knew of a plan which included plans to assassinate his opponent and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute Justice Moraes - the High Court judge who has been presiding over his judicial proceedings.
The plot was stopped because it couldn't obtain the endorsement of the army and air force commanders. The current president was inaugurated without problem on 1 January 2023.
But a seven days after, on the eighth of January, numerous Bolsonaro supporters attacked and damaged government buildings in the federal district, Brazil's capital.
The security forces took action and around 1,500 people were detained.
The judges found that the protesters had been provoked by Bolsonaro whose strategy, they said, was for the Brazilian military to intervene, restore order and bring him back to power.
At the moment, Bolsonaro's lawyers called the decades-long sentence extremely harsh.
He was also banned from campaigning for office until the year 2060 - a decade minus two years after the completion of his term.
The one-time head of state called the court case a targeted investigation" and said it was designed to prevent him competing in the next presidential race.
