The former Brazilian leader has been detained after authorities concluded he posed a concrete flight risk while under house arrest.
The ex-president was sentenced of planning a military coup in the ninth month and handed more than a 27-year term in incarceration, but he was staying under confinement pending appeals.
High Court Judge Alexandre de Moraes said the action to imprison the 70-year-old politician was a safety action after recent developments came to light.
This included attempting to break his tracking device and a call for a public vigil that could facilitate a potential flight.
Judicial Records Show Flight Fears
In a paperwork permitting the detention, Justice Moraes said intelligence from the centre monitoring Bolsonaro's house arrest suggested the ex-president's aim to disable the surveillance device to guarantee victory in his getaway".
This, it said, would be made easier by the confusion caused by the protest called by his son.
His son, Flávio Bolsonaro, who serves as a legislator, called for a gathering of his backers near Bolsonaro's home to take place on the weekend.
Flávio Bolsonaro wrote on social media on Friday: "Are you going to fight for your homeland, or watch it all from your smartphone there on your sofa? I invite you to struggle with us."
He said the gathering would be so followers could "pray for his well-being and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of Justice Moraes's ruling was the possibility of the former president's transfer to foreign missions near the home, considering that the inquiries revealed a background of planning to seek refuge through a diplomatic representation", a statement said.
The legal document highlights that the US embassy in the capital, the capital city, is situated around 8 miles from Bolsonaro's home.
Global Responses
Bolsonaro's legal woes have generated frustration from fellow right-wing populist American leader Donald Trump, causing him to enact a half-rate duty on Brazilian product imports.
Bolsonaro is being kept in a federal law enforcement building in the capital and will undergo a custody hearing on the next day.
Latest Court Petitions
It was only on the previous day that the former president's lawyers asked the Top Court to authorize him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also asked that the former president be authorized to leave his home for healthcare, saying he demanded frequent medical attention for pulmonary infections and other health problems.
Details of Guilty Verdict
He was determined responsible of heading a conspiracy aimed at keeping him in power after he lost the 2022 election to his ideological adversary, President Lula.
Top judicial officials said that he was aware of a plan which encompassed plans to assassinate his opponent and his running partner, Geraldo Alckmin, and to detain and kill Alexandre de Moraes - the High Court judge who has been overseeing Bolsonaro's trial.
The scheme was stopped because it failed to get the support of the military leaders. Lula was took office without incident on the first day of 2023.
But a seven days after, on the eighth of January, many Bolsonaro supporters stormed and vandalised public facilities in the federal district, Brazil's capital.
The police stepped in and around approximately 1,500 persons were taken into custody.
The magistrates found that the protesters had been incited by him whose strategy, they said, was for the national armed forces to take action, restore order and return him to office.
At the moment, Bolsonaro's lawyers called the over 27-year sentence extremely harsh.
He was also barred from campaigning for office until the year 2060 - eight years after the end of his sentence.
The one-time head of state called the trial a targeted investigation" and said it was aimed at blocking him running in the 2026 national vote.
