Bolsonaro has been detained after authorities found he posed a concrete flight risk while under domestic detention.
The former head of state was found guilty of orchestrating a government overthrow in September and given more than over two decades in jail, but he remained under home detention pending legal challenges.
Brazilian Supreme Court Justice Justice Moraes said the decision to arrest the elderly politician was a safety action after fresh information emerged.
This included seeking to disable his tracking device and a call for a public vigil that could "allow for a potential flight.
Judicial Records Show Escape Concerns
In a paperwork permitting the detention, the judge said intelligence from the centre monitoring his home detention suggested the one-time head of state's plan to remove the tracking monitor to secure accomplishment in his escape.
This, it said, would be made easier by the chaos caused by the gathering called by his offspring.
His offspring, Flávio, who works as a legislator, called for a meeting of his supporters near Bolsonaro's home to take place on Saturday evening.
Flávio Bolsonaro wrote on digital networks on Friday: Do you plan to struggle for your homeland, or watch it all from your smartphone there on your settee? I call on you to battle with us."
He said the demonstration would be so supporters could "pray for his physical condition and for the return of democracy in our country."
Embassy Asylum Concerns
Part of Justice Moraes's determination was the chance of his transfer to embassies near the dwelling, considering that the inquiries revealed a background of arranging to seek refuge through a embassy office", a announcement said.
The legal document emphasizes that the United States embassy in the federal district, the capital city, is located around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have generated frustration from fellow right-wing populist United States President Donald Trump, prompting him to impose a 50% tariff on goods coming from Brazil.
The former president is being held 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 the previous day that the ex-leader's attorneys asked the Supreme Court to permit him to fulfill his full incarceration period under house arrest, with digital surveillance.
They also asked that Bolsonaro be authorized to depart his residence for medical treatment, saying he needed ongoing care for respiratory ailments and other illnesses.
Background on Conviction
He was convicted of leading a conspiracy aimed at retaining his authority after he was defeated in the 2022 election to his left-wing rival, Lula.
Top judicial officials said that he had knowledge of a plan which included plans to murder Lula and his vice-presidential running mate, Alckmin, and to imprison and murder the presiding judge - the High Court judge who has been presiding over the former president's case.
The conspiracy was prevented because it didn't receive the support of the armed forces officials. The current president was took office without issue on 1 January 2023.
But a following week, on the eighth of January, numerous his backers stormed and vandalised government buildings in the national capital, Brazil's capital.
The law enforcement stepped in and around fifteen hundred individuals were arrested.
The judges found that the protesters had been incited by him whose plan, they said, was for the country's army to step in, bring back stability and reinstate his authority.
At the time, the legal team called the decades-long sentence unreasonably severe".
He was also barred from seeking elected position until 2060 - a decade minus two years after the conclusion of his imprisonment.
The ex-leader called the trial a political persecution and said it was intended to stop him running in the next presidential race.
