Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under domestic detention.
The one-time leader was sentenced of planning a armed takeover in September and sentenced more than over two decades in jail, but he continued under confinement pending court reviews.
Top Judicial Official Justice Moraes said the move to detain the elderly politician was a preventative measure after "new facts" emerged.
This involved trying to remove his tracking device and a invitation to a public vigil that could "allow for a potential flight.
Legal Document Reveals Flight Fears
In a document approving the detention, the judge said intelligence from the unit overseeing his home detention suggested the former leader's aim to disable the surveillance device to guarantee victory in his flight.
This, it said, would be made easier by the disorder caused by the demonstration called by his child.
His offspring, his son Flávio, who holds office as a senator, called for a meeting of his supporters near Bolsonaro's home to take place on Saturday evening.
The senator wrote on digital networks on Friday: Will you battle for your homeland, or observe everything from your smartphone there on your settee? I invite you to fight with us."
He said the demonstration would be so supporters could seek divine intervention for his health and for the restoration of democratic rule in our nation."
Foreign Shelter Risks
Part of Justice Moraes's determination was the chance of the former president's move to diplomatic missions near the home, considering that the inquiries revealed a background of arranging to seek refuge through a consular facility", a announcement said.
The court filing highlights that the American diplomatic mission in the national capital, Brasilia, is positioned around 13km from the former president's residence.
Worldwide Consequences
The former president's legal troubles have drawn the ire of fellow conservative nationalist US President Donald Trump, causing him to implement a half-rate duty on goods coming from Brazil.
The former president is being held in a national police facility in Brasilia and will experience a custody hearing on the following day.
Latest Court Petitions
It was only on last Friday that the former president's lawyers asked the Top Court to authorize him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also petitioned that the former president be allowed to exit his dwelling for medical treatment, saying he required frequent medical attention for pulmonary infections and other health problems.
Details of Guilty Verdict
Bolsonaro was convicted of orchestrating a conspiracy aimed at retaining his authority after he lost the 2022 election to his left-wing rival, Lula.
Supreme Court justices said that he had knowledge of a scheme which included plans to murder Lula and his VP candidate, Geraldo Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been presiding over the former president's case.
The plot was prevented because it failed to get the endorsement of the armed forces officials. Lula was inaugurated without issue on the first day of 2023.
But a following week, on 8 January, many Bolsonaro supporters attacked and damaged official structures in the federal district, Brasília.
The police stepped in and around 1,500 people were detained.
The magistrates found that the demonstrators had been encouraged by Bolsonaro whose scheme, they said, was for the national armed forces to step in, bring back stability and bring him back to power.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence unreasonably severe".
He was also prohibited from seeking elected position until the year 2060 - eight years later after the conclusion of his imprisonment.
The one-time head of state called the court case a targeted investigation" and said it was aimed at blocking him participating in the next presidential race.
