The former Brazilian leader has been taken into custody after authorities determined he posed a definite escape threat while under house arrest.
The former head of state was sentenced of planning a armed takeover in September and sentenced more than a 27-year term in jail, but he was staying under confinement pending appeals.
High Court Judge Alexandre de Moraes said the action to imprison the elderly politician was a preventative measure after "new facts" emerged.
This encompassed trying to remove his ankle monitor and a call for a public vigil that could "allow for a chance to flee".
Legal Document Reveals Flight Fears
In a paperwork permitting the detention, Justice Moraes said data from the centre monitoring Bolsonaro's house arrest suggested the ex-president's aim to disable the electronic ankle bracelet to ensure success in his getaway".
This, it said, would be made easier by the chaos caused by the demonstration called by his offspring.
His son, Flávio, who holds office as a congressional representative, called for a assembly of his backers near Bolsonaro's home to take place on Saturday night.
The senator wrote on online platforms on last Friday: Will you battle for your nation, or see it all from your mobile device there on your settee? I invite you to struggle with us."
He said the gathering would be so followers could seek divine intervention for his well-being and for the return of democracy in our land."
Embassy Asylum Concerns
Part of the judge's ruling was the chance of his move to foreign missions near the residence, considering that the investigations revealed a background of arranging to ask for protection through a embassy office", a declaration said.
The court filing emphasizes that the United States embassy in the federal district, the capital city, is situated around approximately 13 kilometers from the former president's residence.
Worldwide Consequences
His judicial problems have generated frustration from fellow conservative nationalist US President President Trump, prompting him to impose a fifty percent tax on goods coming from Brazil.
Bolsonaro is being kept in a federal law enforcement building in Brazil's capital city and will have a detention review on the next day.
Latest Court Petitions
It was only on last Friday that the his legal team asked the Top Court to permit him to fulfill his full incarceration period under home confinement, with digital surveillance.
They also asked that he be authorized to leave his home for medical treatment, saying he demanded regular treatment for lung conditions and other ailments.
Background on Conviction
The former president was determined responsible of heading a conspiracy aimed at maintaining his control after he lost the presidential race to his left-wing rival, Lula.
High Court judges said that he had knowledge of a plot which involved plans to kill Lula and his VP candidate, his vice-presidential candidate, and to arrest and execute the presiding judge - the top judicial official who has been presiding over his judicial proceedings.
The plot was prevented because it failed to get the backing of the armed forces officials. His successor was took office without issue on 1 January 2023.
But a seven days after, on January 8th, thousands of his backers attacked and damaged public facilities in the capital, Brazil's capital.
The security forces intervened and around 1,500 people were taken into custody.
The magistrates found that the rioters had been provoked by Bolsonaro whose plan, they said, was for the Brazilian military to intervene, restore order and return him to office.
At the period, his attorneys called the 27 years and three months sentence extremely harsh.
He was also barred from campaigning for office until 2060 - a decade minus two years after the completion of his term.
The ex-leader called the court case a "witch hunt and said it was aimed at blocking him competing in the 2026 presidential election.
