Bolsonaro has been detained after authorities determined he posed a concrete flight risk while under domestic detention.
The one-time leader was sentenced of plotting a military coup in September and handed more than over two decades in jail, but he continued under confinement pending legal challenges.
Brazilian Supreme Court Justice the presiding justice said the decision to arrest the elderly politician was a safety action after "new facts" were revealed.
This encompassed trying to remove his ankle monitor and a call for a public vigil that could "allow for a potential flight.
Legal Document Reveals Flight Fears
In a filing authorising the detention, the judge said data from the facility tracking the former president's confinement suggested the former leader's aim to disable the surveillance device to guarantee victory in his getaway".
This, it said, would be made easier by the chaos caused by the demonstration called by his son.
His son, his son Flávio, who holds office as a senator, called for a assembly of his supporters near his father's house to take place on Saturday night.
His son wrote on digital networks on Friday: "Are you going to fight for your homeland, or observe everything from your mobile device there on your couch? I invite you to battle with us."
He said the demonstration would be so supporters could seek divine intervention for his physical condition and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of his transfer to diplomatic missions near the residence, considering that the investigations revealed a record of arranging to seek refuge through a diplomatic representation", a declaration said.
The court filing highlights that the United States embassy in the federal district, Brasilia, is positioned around 13km from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have drawn the ire of fellow right-wing populist American leader President Trump, causing him to enact a half-rate duty on goods coming from Brazil.
He is being held in a federal law enforcement building in Brazil's capital city and will undergo a detention review on Sunday.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the Supreme Court to permit him to fulfill his full incarceration period under domestic detention, with digital surveillance.
They also petitioned that he be allowed to depart his residence for medical treatment, saying he required regular treatment for respiratory ailments and other health problems.
Details of Guilty Verdict
Bolsonaro was found guilty of heading a scheme 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 plan which involved plans to murder the current president and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder the presiding judge - the Supreme Court justice who has been overseeing the former president's case.
The scheme was thwarted because it couldn't obtain the support of the army and air force commanders. The current president was sworn in without problem on 1 January 2023.
But a seven days after, on 8 January, many his followers stormed and vandalised government buildings in the capital, Brasília.
The security forces intervened and around 1,500 people were taken into custody.
The judges found that the demonstrators had been provoked by him whose plan, they said, was for the Brazilian military to take action, bring back stability and return him to office.
At the period, Bolsonaro's lawyers called the 27 years and three months sentence unreasonably severe".
He was also barred from campaigning for office until the year 2060 - eight years later after the end of his sentence.
The former president called the legal proceedings a targeted investigation" and said it was designed to prevent him competing in the 2026 national vote.
