Bolsonaro has been arrested after authorities determined he posed a concrete flight risk while under home confinement.
The ex-president was sentenced of planning a military coup in September and handed more than a 27-year term in prison, but he was staying under confinement pending appeals.
Brazilian Supreme Court Justice Alexandre de Moraes said the decision to arrest the 70-year-old politician was a preventative measure after fresh information were revealed.
This involved attempting to break his tracking device and a invitation to a demonstration that could "allow for a chance to flee".
Legal Document Reveals Escape Risks
In a paperwork permitting the custody, the judge said data from the unit overseeing his home detention suggested the one-time head of state's aim to disable the electronic ankle bracelet to guarantee victory in his getaway".
This, it said, would be made easier by the chaos caused by the gathering called by his child.
His son, Flávio Bolsonaro, who works as a congressional representative, called for a gathering of his backers near the former president's residence to take place on Saturday evening.
The senator wrote on digital networks on Friday: "Are you going to fight for your nation, or watch it all from your mobile device there on your settee? I invite you to fight with us."
He said the demonstration would be so backers could offer prayers for his physical condition and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of Justice Moraes's determination was the potential of his move to embassies near the dwelling, considering that the inquiries revealed a background of arranging to seek refuge through a consular facility", a announcement said.
The judicial paperwork underscores that the United States embassy in the capital, Brazil's capital, is situated around 8 miles from Bolsonaro's home.
Global Responses
His judicial problems have generated frustration from fellow populist conservative American leader President Trump, prompting him to implement a 50% tariff on imports of Brazilian goods.
Bolsonaro is being held in a federal law enforcement building in Brazil's capital city and will undergo a custody hearing on the next day.
Latest Court Petitions
It was only on Friday that the his legal team asked the Supreme Court to authorize him to complete his entire prison term under domestic detention, with electronic monitoring.
They also petitioned that the former president be allowed to leave his home for medical care, saying he required frequent medical attention for lung conditions and other ailments.
Details of Guilty Verdict
He was found guilty of leading a conspiracy aimed at retaining his authority after he failed to win the 2022 election to his ideological adversary, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a plot which included plans to kill his opponent and his VP candidate, Alckmin, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been managing his judicial proceedings.
The plot was thwarted because it didn't receive the endorsement of the military leaders. His successor was sworn in without issue on 1 January 2023.
But a following week, on January 8th, thousands of his followers stormed and vandalised government buildings in the capital, Brasília.
The police stepped in and around approximately 1,500 persons were detained.
The judges found that the demonstrators had been incited by him whose scheme, they said, was for the Brazilian military to take action, restore order and return him to office.
At the time, the legal team called the decades-long sentence unreasonably severe".
He was also prohibited from campaigning for office until 2060 - eight years after the end of his sentence.
The former president called the legal proceedings a political persecution and said it was aimed at blocking him running in the next presidential race.
