Bolsonaro has been detained after authorities determined he posed a definite escape threat while under home confinement.
The former head of state was convicted of plotting a government overthrow in last fall and handed more than over two decades in jail, but he was staying under house arrest pending legal challenges.
Top Judicial Official the presiding justice said the decision to arrest the septuagenarian politician was a safety action after "new facts" were revealed.
This included trying to remove his ankle monitor and a invitation to a demonstration that could "allow for a possible escape.
Court Filing Details Flight Fears
In a filing authorising the arrest, the magistrate said intelligence from the centre monitoring the former president's confinement suggested the former leader's aim to disable the electronic ankle bracelet to guarantee victory in his escape.
This, it said, would be made easier by the disorder caused by the gathering called by his son.
His offspring, his son Flávio, who serves as a legislator, called for a gathering of his followers near his father's house to take place on Saturday evening.
Flávio Bolsonaro wrote on social media on the previous day: "Are you going to fight for your country, or see it all from your mobile device there on your sofa? I call on you to struggle with us."
He said the demonstration would be so backers could "pray for his health and for the restoration of democratic rule in our land."
Embassy Asylum Concerns
Part of Justice Moraes's ruling was the potential of the former president's "relocation to foreign missions near the residence, considering that the probes revealed a history of organizing to request asylum through a consular facility", a announcement said.
The legal document highlights that the American diplomatic mission in the federal district, the capital city, is positioned around 8 miles from Bolsonaro's home.
Global Responses
His judicial problems have generated frustration from fellow conservative nationalist American leader Trump, leading him to enact a half-rate duty on Brazilian product imports.
He is being held in a federal law enforcement building in Brazil's capital city and will experience a detention review on Sunday.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the High Court to allow him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also petitioned that he be permitted to depart his residence for medical treatment, saying he demanded ongoing care for pulmonary infections and other health problems.
Details of Guilty Verdict
The former president was convicted of heading a conspiracy aimed at retaining his authority after he lost the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
Top judicial officials said that he was aware of a scheme which encompassed plans to murder the current president and his vice-presidential running mate, his vice-presidential candidate, and to arrest and execute the presiding judge - the High Court judge who has been managing his judicial proceedings.
The conspiracy was stopped because it didn't receive the support of the military leaders. Lula was inaugurated without incident on 1 January 2023.
But a week later, on 8 January, many his backers attacked and damaged official structures in the federal district, Brasília.
The police intervened and around approximately 1,500 persons were taken into custody.
The justices found that the demonstrators had been provoked by Bolsonaro whose plan, they said, was for the national armed forces to intervene, reestablish control and reinstate his authority.
At the time, Bolsonaro's lawyers called the over 27-year sentence unreasonably severe".
He was also barred from seeking elected position until twenty-sixty - a decade minus two years after the end of his sentence.
The ex-leader called the court case a targeted investigation" and said it was designed to prevent him competing in the next presidential race.
