Bolsonaro has been detained after authorities concluded he posed a concrete flight risk while under house arrest.
The one-time leader was found guilty of plotting a armed takeover in last fall and handed more than a 27-year term in incarceration, but he continued under house arrest pending appeals.
Top Judicial Official Justice Moraes said the move to detain the septuagenarian politician was a precautionary step after recent developments came to light.
This encompassed seeking to disable his ankle monitor and a call for a supporters' gathering that could "allow for a potential flight.
Legal Document Reveals Escape Concerns
In a paperwork permitting the custody, Justice Moraes said data from the unit overseeing Bolsonaro's house arrest suggested the one-time head of state's "intention to break the surveillance device to secure accomplishment in his flight.
This, it said, would be "facilitated by the disorder caused by the gathering called by his child.
His son, Flávio Bolsonaro, who works as a senator, called for a meeting of his backers near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on online platforms on the previous day: Do you plan to struggle for your nation, or watch it all from your smartphone there on your settee? I call on you to fight with us."
He said the vigil would be so backers could offer prayers for his health and for the return of democracy in our land."
Foreign Shelter Risks

Context of Sentencing
Bolsonaro was determined responsible of orchestrating a plot aimed at maintaining his control after he failed to win the 2022 election to his political opponent, Lula.

At the moment, Bolsonaro's lawyers called the decades-long sentence extremely harsh.
He was also banned from seeking elected position until the year 2060 - eight years after the completion of his term.
