Bolsonaro has been detained after authorities found he posed a serious risk of fleeing while under domestic detention.
The ex-president was found guilty of orchestrating a government overthrow in the ninth month and given more than over two decades in prison, but he remained under home detention pending legal challenges.
High Court Judge the presiding justice said the move to detain the elderly politician was a precautionary step after recent developments emerged.
This encompassed seeking to disable his electronic bracelet and a call for a demonstration that could "allow for a chance to flee".
Judicial Records Show Flight Fears
In a document approving the detention, the magistrate said intelligence from the unit overseeing his home detention suggested the former leader's aim to disable the tracking monitor to guarantee victory in his escape.
This, it said, would be "facilitated by the chaos caused by the gathering called by his child.
His child, Flávio, who serves as a legislator, called for a assembly of his backers near his father's house to take place on the weekend.
His son wrote on online platforms on last Friday: Do you plan to struggle for your country, or see it all from your smartphone there on your couch? I call on you to battle with us."
He said the vigil would be so backers could offer prayers for his well-being and for the return of democracy in our country."
Foreign Shelter Risks
Part of the judge's ruling was the potential of Bolsonaro's move to foreign missions near the residence, considering that the probes revealed a record of arranging to request asylum through a embassy office", a declaration said.
The legal document emphasizes that the US embassy in the federal district, Brazil's capital, is located around approximately 13 kilometers from his dwelling.
Global Responses
His judicial problems have generated frustration from fellow populist conservative United States President President Trump, causing him to impose a 50% tariff on Brazilian product imports.
He is being kept in a national police facility in Brasilia and will experience a detention review on Sunday.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the Top Court to authorize him to serve his whole jail sentence under domestic detention, with electronic monitoring.
They also asked that Bolsonaro be authorized to leave his home for medical treatment, saying he needed frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
He was convicted of leading a scheme aimed at keeping him in power after he lost the national vote to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he was aware of a plan which included plans to assassinate the current president and his vice-presidential running mate, Alckmin, and to detain and kill Alexandre de Moraes - the top judicial official who has been presiding over Bolsonaro's trial.
The scheme was stopped because it didn't receive the backing of the armed forces officials. His successor was inaugurated without issue on January 1st, 2023.
But a following week, on the eighth of January, many Bolsonaro supporters stormed and vandalised public facilities in the federal district, Brazil's capital.
The law enforcement took action and around approximately 1,500 persons were detained.
The magistrates found that the demonstrators had been incited by Bolsonaro whose plan, they said, was for the country's army to take action, reestablish control and return him to office.
At the moment, Bolsonaro's lawyers called the 27 years and three months sentence "absurdly excessive.
He was also prohibited from campaigning for office until the year 2060 - a decade minus two years after the end of his sentence.
The one-time head of state called the legal proceedings a political persecution and said it was aimed at blocking him running in the next presidential race.
