Bolsonaro has been detained after authorities found he posed a serious risk of fleeing while under home confinement.
The former head of state was convicted of plotting a military coup in the ninth month and given more than over two decades in jail, but he continued under home detention pending legal challenges.
High Court Judge the presiding justice said the action to imprison the septuagenarian politician was a preventative measure after recent developments were revealed.
This encompassed seeking to disable his tracking device and a call for a public vigil that could "allow for a possible escape.
Judicial Records Show Escape Risks
In a document approving the arrest, the magistrate said intelligence from the unit overseeing Bolsonaro's house arrest suggested the ex-president's plan to remove the electronic ankle bracelet to guarantee victory in his escape.
This, it said, would be made easier by the confusion caused by the gathering called by his son.
His son, his son Flávio, who serves as a senator, called for a gathering of his supporters near Bolsonaro's home to take place on Saturday night.
His son wrote on digital networks on last Friday: Will you battle for your homeland, or see it all from your phone there on your couch? I call on you to struggle with us."
He said the gathering would be so followers could seek divine intervention for his health and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of the magistrate's determination was the chance of Bolsonaro's transfer to diplomatic missions near the residence, considering that the inquiries revealed a record of planning to seek refuge through a embassy office", a announcement said.
The court filing highlights that the United States embassy in the federal district, the capital city, is located around approximately 13 kilometers from his dwelling.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow right-wing populist American leader President Trump, causing him to impose a half-rate duty on imports of Brazilian goods.
Bolsonaro is being kept in a federal law enforcement building in Brasilia and will experience a imprisonment assessment on the next day.
Latest Court Petitions
It was only on Friday that the his legal team asked the Top Court to authorize him to complete his entire prison term under home confinement, with tracking devices.
They also petitioned that he be permitted to leave his home for medical care, saying he required regular treatment for lung conditions and other illnesses.
Details of Guilty Verdict
He was determined responsible of orchestrating a conspiracy aimed at maintaining his control after he was defeated in the national vote to his left-wing rival, Lula.
Supreme Court justices said that he knew of a scheme which included plans to assassinate Lula and his vice-presidential running mate, Geraldo Alckmin, and to detain and kill Alexandre de Moraes - the Supreme Court justice who has been overseeing Bolsonaro's trial.
The conspiracy was prevented because it didn't receive the endorsement of the military leaders. The current president was inaugurated without incident on 1 January 2023.
But a week later, on the eighth of January, thousands of his backers stormed and vandalised government buildings in the national capital, Brasília.
The law enforcement intervened and around fifteen hundred individuals were taken into custody.
The justices found that the rioters had been encouraged by Bolsonaro whose scheme, they said, was for the Brazilian military to step in, bring back stability and bring him back to power.
At the time, the legal team called the 27 years and three months sentence extremely harsh.
He was also barred from campaigning for office until the year 2060 - eight years after the conclusion of his imprisonment.
The one-time head of state called the court case a "witch hunt and said it was intended to stop him competing in the next presidential race.
