The former Brazilian leader has been taken into custody after authorities concluded he posed a serious risk of fleeing while under home confinement.
The former head of state was convicted of plotting a military coup in last fall and given more than a 27-year term in prison, but he remained under confinement pending appeals.
High Court Judge the presiding justice said the move to detain the elderly politician was a safety action after fresh information emerged.
This included seeking to disable his ankle monitor and a call for a public vigil that could enable a potential flight.
Court Filing Details Flight Fears
In a paperwork permitting the detention, the magistrate said data from the unit overseeing his home detention suggested the former leader's aim to disable the tracking monitor to guarantee victory in his getaway".
This, it said, would be assisted by the confusion caused by the protest called by his son.
His son, Flávio Bolsonaro, who serves as a legislator, called for a assembly of his backers near Bolsonaro's home to take place on Saturday night.
The senator wrote on digital networks on Friday: "Are you going to fight for your nation, or observe everything from your smartphone there on your settee? I invite you to struggle with us."
He said the vigil would be so backers could "pray for his well-being and for the return of democracy in our land."
Diplomatic Refuge Fears
Part of the judge's ruling was the possibility of his move to diplomatic missions near the dwelling, considering that the probes revealed a record of arranging to request asylum through a consular facility", a declaration said.
The legal document underscores that the American diplomatic mission in the capital, Brasilia, is positioned around 13km from the former president's residence.
Worldwide Consequences
Bolsonaro's legal woes have provoked anger from fellow right-wing populist US President Donald Trump, causing him to implement a half-rate duty on goods coming from Brazil.
Bolsonaro is being held in a federal law enforcement building in Brasilia and will undergo a imprisonment assessment on the following day.
Recent Legal Requests
It was only on last Friday that the former president's lawyers asked the Supreme Court to allow him to serve his whole jail sentence under house arrest, with digital surveillance.
They also petitioned that he be authorized to depart his residence for medical treatment, saying he required frequent medical attention for lung conditions and other ailments.
Details of Guilty Verdict

Top judicial officials said that he was aware of a plan which included plans to assassinate Lula and his running partner, his vice-presidential candidate, and to detain and kill Alexandre de Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The conspiracy was stopped because it couldn't obtain the endorsement of the military leaders. Lula was took office without problem on January 1st, 2023.
But a seven days after, on January 8th, numerous his followers invaded and destroyed official structures in the capital, the capital city.
The law enforcement intervened 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 country's army to step in, restore order and bring him back to power.
At the period, Bolsonaro's lawyers called the over 27-year sentence unreasonably severe".
