The former Brazilian leader has been detained after authorities found he posed a definite escape threat while under house arrest.
The one-time leader was convicted of plotting a government overthrow in September and given more than over two decades in incarceration, but he was staying under confinement pending appeals.
High Court Judge Justice Moraes said the move to detain the elderly politician was a preventative measure after "new facts" emerged.
This involved attempting to break his electronic bracelet and a call for a supporters' gathering that could facilitate a potential flight.
Legal Document Reveals Flight Fears
In a paperwork permitting the custody, the magistrate said intelligence from the centre monitoring his home detention suggested the one-time head of state's plan to remove the surveillance device to guarantee victory in his escape.
This, it said, would be made easier by the confusion caused by the gathering called by his child.
His child, Flávio, who holds office as a congressional representative, called for a meeting of his supporters near his father's house to take place on Saturday night.
His son wrote on digital networks on the previous day: "Are you going to fight for your homeland, or watch it all from your smartphone there on your settee? I invite you to battle with us."
He said the gathering would be so followers could seek divine intervention for his health and for the return of democracy in our land."
Diplomatic Refuge Fears
Part of Justice Moraes's decision was the potential of Bolsonaro's transfer to diplomatic missions near the dwelling, considering that the inquiries revealed a background of planning to seek refuge through a embassy office", a announcement said.
The judicial paperwork emphasizes that the United States embassy in the national capital, Brasilia, is located around approximately 13 kilometers from his dwelling.
International Reactions
The former president's legal troubles have drawn the ire of fellow conservative nationalist American leader Trump, causing him to implement a half-rate duty on Brazilian product imports.
The former president is being held in a Federal Police station in Brasilia and will have a imprisonment assessment on Sunday.
Latest Court Petitions
It was only on last Friday that the ex-leader's attorneys asked the High Court to allow him to serve his whole jail sentence under home confinement, with electronic monitoring.
They also asked that he be allowed to depart his residence for medical treatment, saying he needed regular treatment for respiratory ailments and other ailments.
Details of Guilty Verdict
Bolsonaro was determined responsible of leading a plot aimed at keeping him in power after he failed to win the 2022 election to his left-wing rival, President Lula.

But a seven days after, on the eighth of January, numerous his followers stormed and vandalised government buildings in the federal district, Brazil's capital.
The security forces took action and around approximately 1,500 persons were taken into custody.
The judges found that the rioters had been encouraged by Bolsonaro whose strategy, they said, was for the country's army to intervene, restore order and bring him back to power.
At the moment, his attorneys called the decades-long sentence unreasonably severe".
He was also barred from running for public office until the year 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the court case a political persecution and said it was designed to prevent him participating in the 2026 presidential election.
