Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under house arrest.
The former head of state was sentenced of plotting a armed takeover in the ninth month and handed more than a 27-year term in incarceration, but he was staying under home detention pending court reviews.
High Court Judge Alexandre de Moraes said the action to imprison the elderly politician was a precautionary step after fresh information came to light.
This involved attempting to break his electronic bracelet and a summons to a demonstration that could enable a possible escape.
Court Filing Details Escape Concerns
In a filing authorising the detention, Justice Moraes said data from the centre monitoring Bolsonaro's house arrest suggested the one-time head of state's "intention to break the electronic ankle bracelet to ensure success in his escape.
This, it said, would be made easier by the disorder caused by the protest called by his child.
His son, Flávio Bolsonaro, who serves as a legislator, called for a meeting of his supporters near the former president's residence to take place on Saturday night.
His son wrote on digital networks on the previous day: Do you plan to struggle for your homeland, or watch it all from your mobile device there on your couch? I urge you to struggle with us."
He said the vigil would be so supporters could offer prayers for his physical condition and for the return of democracy in our land."
Foreign Shelter Risks
Part of the judge's ruling was the chance of Bolsonaro's move to foreign missions near the dwelling, considering that the probes revealed a background of arranging to seek refuge through a embassy office", a statement said.
The court filing emphasizes that the US embassy in the capital, Brasilia, is situated around approximately 13 kilometers from Bolsonaro's home.
International Reactions
His judicial problems have drawn the ire of fellow populist conservative American leader Trump, prompting him to implement a half-rate duty on imports of Brazilian goods.
Bolsonaro is being detained in a national police facility in Brazil's capital city and will undergo a custody hearing on Sunday.
Recent Legal Requests
It was only on the previous day that the ex-leader's attorneys asked the High Court to allow him to fulfill his full incarceration period under home confinement, with tracking devices.
They also petitioned that Bolsonaro be permitted to exit his dwelling for medical treatment, saying he needed ongoing care for pulmonary infections and other ailments.
Details of Guilty Verdict
The former president was convicted of leading a scheme aimed at retaining his authority after he lost the presidential race to his ideological adversary, Luiz Inácio Lula da Silva.
Top judicial officials said that he was aware of a plan which encompassed plans to kill his opponent and his running partner, Alckmin, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been overseeing his judicial proceedings.
The scheme was stopped because it couldn't obtain the support of the army and air force commanders. His successor was sworn in without incident on the first day of 2023.
But a following week, on 8 January, numerous Bolsonaro supporters stormed and vandalised government buildings in the national capital, Brazil's capital.
The police intervened and around fifteen hundred individuals were arrested.
The justices found that the protesters had been encouraged by the former president whose strategy, they said, was for the Brazilian military to intervene, restore order and bring him back to power.
At the time, his attorneys called the over 27-year sentence unreasonably severe".
He was also banned from running for public office until the year 2060 - eight years later after the completion of his term.
The former president called the court case a political persecution and said it was intended to stop him running in the next presidential race.
