Bolsonaro has been taken into custody after authorities determined he posed a serious risk of fleeing while under house arrest.
The former head of state was found guilty of plotting a military coup in the ninth month and handed more than a 27-year term in prison, but he remained under confinement pending legal challenges.
High Court Judge the presiding justice said the action to imprison the 70-year-old politician was a precautionary step after "new facts" were revealed.
This involved attempting to break his electronic bracelet and a call for a demonstration that could enable a possible escape.
Judicial Records Show Escape Concerns
In a document approving the arrest, the magistrate said data from the unit overseeing the former president's confinement suggested the ex-president's aim to disable the tracking monitor to guarantee victory in his escape.
This, it said, would be "facilitated by the confusion caused by the protest called by his offspring.
His son, Flávio Bolsonaro, who serves as a senator, called for a meeting of his followers near the former president's residence to take place on Saturday night.
The senator wrote on online platforms on the previous day: Will you battle for your nation, or observe everything from your phone there on your settee? I call on you to struggle with us."
He said the demonstration would be so backers could offer prayers for his physical condition and for the return of democracy in our country."
Embassy Asylum Concerns
Part of the magistrate's ruling was the chance of the former president's transfer to foreign missions near the residence, considering that the probes revealed a record of planning to request asylum through a diplomatic representation", a declaration said.
The judicial paperwork highlights that the American diplomatic mission in the capital, Brazil's capital, is situated around 13km from his dwelling.
Global Responses
Bolsonaro's legal woes have drawn the ire of fellow right-wing populist American leader Donald Trump, leading him to impose a fifty percent tax on imports of Brazilian goods.
He is being kept in a national police facility in Brazil's capital city and will have a imprisonment assessment on the following day.
Recent Legal Requests
It was only on last Friday that the his legal team asked the High Court to permit him to fulfill his full incarceration period under domestic detention, with electronic monitoring.
They also asked that he be authorized to leave his home for medical care, saying he demanded regular treatment for lung conditions and other ailments.
Context of Sentencing
The former president was convicted of heading a scheme aimed at retaining his authority after he was defeated in the national vote to his political opponent, Lula.
High Court judges said that he was aware of a plot which included plans to assassinate Lula and his VP candidate, his vice-presidential candidate, and to arrest and execute the presiding judge - the High Court judge who has been overseeing Bolsonaro's trial.
The plot was prevented because it failed to get the backing of the army and air force commanders. His successor was took office without issue on the first day of 2023.
But a week later, on January 8th, many his backers attacked and damaged official structures in the national capital, Brazil's capital.
The police stepped in and around approximately 1,500 persons were arrested.
The justices found that the demonstrators had been provoked by the former president whose strategy, they said, was for the Brazilian military to step in, bring back stability and reinstate his authority.
At the period, the legal team called the over 27-year sentence unreasonably severe".
He was also barred from campaigning for office until twenty-sixty - a decade minus two years after the end of his sentence.
The former president called the court case a "witch hunt and said it was designed to prevent him competing in the 2026 presidential election.
