Bolsonaro has been detained after authorities determined he posed a definite escape threat while under domestic detention.
The former head of state was sentenced of planning a armed takeover in September and given more than 27 years in incarceration, but he continued under home detention pending appeals.
High Court Judge Justice Moraes said the decision to arrest the 70-year-old politician was a precautionary step after fresh information came to light.
This encompassed seeking to disable his ankle monitor and a invitation to a supporters' gathering that could facilitate a possible escape.
Legal Document Reveals Escape Concerns
In a document approving the custody, Justice Moraes said information from the facility tracking Bolsonaro's house arrest suggested the former leader's aim to disable the electronic ankle bracelet to guarantee victory in his escape.
This, it said, would be "facilitated by the confusion caused by the demonstration called by his child.
His son, his son Flávio, who holds office as a senator, called for a assembly of his supporters near Bolsonaro's home to take place on Saturday night.
His son wrote on social media on last Friday: Do you plan to struggle for your homeland, or watch it all from your mobile device there on your settee? I call on you to fight with us."
He said the gathering would be so followers could "pray for his well-being and for the return of democracy in our nation."
Diplomatic Refuge Fears
Part of the magistrate's ruling was the chance of the former president's transfer to diplomatic missions near the residence, considering that the inquiries revealed a history of arranging to seek refuge through a embassy office", a statement said.
The court filing underscores that the US embassy in the capital, Brazil's capital, is positioned around 8 miles from Bolsonaro's home.
Global Responses
His judicial problems have provoked anger from fellow conservative nationalist American leader Donald Trump, prompting him to enact a half-rate duty on goods coming from Brazil.
Bolsonaro is being kept in a Federal Police station in Brazil's capital city and will undergo a imprisonment assessment on the next day.
Recent Legal Requests
It was only on last Friday that the ex-leader's attorneys asked the High Court to authorize him to fulfill his full incarceration period under domestic detention, with digital surveillance.
They also petitioned that he be authorized to depart his residence for medical care, saying he required regular treatment for pulmonary infections and other health problems.
Background on Conviction
He was found guilty of leading a plot aimed at retaining his authority after he lost the 2022 election to his ideological adversary, Lula.
High Court judges said that he had knowledge of a plot which encompassed plans to kill his opponent and his vice-presidential running mate, Geraldo Alckmin, and to imprison and murder the presiding judge - the top judicial official who has been managing the former president's case.
The plot was prevented because it failed to get the endorsement of the armed forces officials. His successor was took office without problem on the first day of 2023.
But a seven days after, on the eighth of January, numerous his followers invaded and destroyed government buildings in the capital, Brazil's capital.
The security forces intervened and around fifteen hundred individuals were taken into custody.
The judges found that the demonstrators had been provoked by him whose scheme, they said, was for the Brazilian military to intervene, bring back stability and reinstate his authority.
At the period, his attorneys called the decades-long sentence "absurdly excessive.
He was also prohibited from running for public office until 2060 - eight years after the completion of his term.
The former president called the court case a "witch hunt and said it was intended to stop him competing in the next presidential race.
