Bolsonaro has been arrested after authorities found he posed a serious risk of fleeing while under home confinement.
The one-time leader was found guilty of planning a armed takeover in last fall and given more than 27 years in incarceration, but he was staying under confinement pending legal challenges.
Top Judicial Official the presiding justice said the move to detain the 70-year-old politician was a safety action after fresh information emerged.
This encompassed seeking to disable his tracking device and a summons to a demonstration that could enable a possible escape.
Judicial Records Show Escape Risks
In a filing authorising the custody, the judge said data from the facility tracking his home detention suggested the ex-president's aim to disable the tracking monitor to guarantee victory in his getaway".
This, it said, would be made easier by the confusion caused by the gathering called by his child.
His offspring, Flávio, who holds office as a senator, called for a assembly of his followers near Bolsonaro's home to take place on Saturday night.
Flávio Bolsonaro wrote on digital networks on last Friday: "Are you going to fight for your nation, or watch it all from your phone there on your couch? I invite you to struggle with us."
He said the demonstration would be so backers could offer prayers for his health and for the return of democracy in our country."
Diplomatic Refuge Fears
Part of the judge's ruling was the possibility of the former president's transfer to embassies near the home, considering that the investigations revealed a history of arranging to seek refuge through a consular facility", a statement said.
The court filing highlights that the American diplomatic mission in the capital, the capital city, is situated around 8 miles from Bolsonaro's home.
Worldwide Consequences
The former president's legal troubles have provoked anger from fellow conservative nationalist American leader President Trump, causing him to implement a fifty percent tax on goods coming from Brazil.
The former president is being detained in a federal law enforcement building in the capital and will have a detention review on the next day.
Recent Judicial Appeals
It was only on the previous day that the his legal team asked the High Court to permit him to serve his whole jail sentence under house arrest, with electronic monitoring.
They also asked that the former president be authorized to depart his residence for medical care, saying he needed regular treatment for pulmonary infections and other health problems.
Context of Sentencing
Bolsonaro was determined responsible of orchestrating a conspiracy aimed at maintaining his control after he failed to win the presidential race to his ideological adversary, Lula.
High Court judges said that he had knowledge of a plot which included plans to kill Lula and his running partner, Geraldo Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been managing his judicial proceedings.
The plot was prevented because it couldn't obtain the backing of the military leaders. His successor was sworn in without incident on 1 January 2023.
But a seven days after, on 8 January, thousands of Bolsonaro supporters stormed and vandalised public facilities in the capital, Brasília.
The security forces intervened and around fifteen hundred individuals were taken into custody.
The judges found that the protesters had been incited by Bolsonaro whose scheme, they said, was for the national armed forces to take action, bring back stability and return him to office.
At the moment, his attorneys called the decades-long sentence "absurdly excessive.
He was also barred from campaigning for office until twenty-sixty - eight years after the conclusion of his imprisonment.
The one-time head of state called the trial a targeted investigation" and said it was designed to prevent him competing in the 2026 presidential election.
