Bolsonaro has been arrested after authorities determined he posed a serious risk of fleeing while under home confinement.
The ex-president was found guilty of plotting a government overthrow in September and given more than 27 years in incarceration, but he remained under home detention pending appeals.
High Court Judge Justice Moraes said the move to detain the septuagenarian politician was a safety action after fresh information emerged.
This included attempting to break his tracking device and a summons to a public vigil that could enable a chance to flee".
Judicial Records Show Flight Fears
In a paperwork permitting the arrest, the judge said information from the centre monitoring his home detention suggested the one-time head of state's aim to disable the electronic ankle bracelet to ensure success in his flight.
This, it said, would be made easier by the disorder caused by the protest called by his son.
His child, Flávio, who holds office as a senator, called for a meeting of his backers near the former president's residence to take place on Saturday night.
The senator wrote on digital networks on last Friday: "Are you going to fight for your nation, or observe everything from your mobile device there on your settee? I call on you to fight with us."
He said the gathering would be so backers could "pray for his health and for the return of democracy in our land."
Diplomatic Refuge Fears
Part of Justice Moraes's ruling was the potential of his "relocation to diplomatic missions near the home, considering that the inquiries revealed a history of organizing to seek refuge through a embassy office", a statement said.
The court filing emphasizes that the US embassy in the national capital, the capital city, is situated around approximately 13 kilometers from the former president's residence.
International Reactions
Bolsonaro's legal woes have generated frustration from fellow populist conservative US President President Trump, prompting him to implement a half-rate duty on goods coming from Brazil.
Bolsonaro is being detained in a Federal Police station in Brasilia and will experience a detention review on the following day.
Recent Judicial Appeals
It was only on Friday that the ex-leader's attorneys asked the High Court to authorize him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also requested that the former president be permitted to exit his dwelling for medical care, saying he needed ongoing care for respiratory ailments and other illnesses.
Context of Sentencing
He was determined responsible of heading a scheme aimed at retaining his authority after he lost the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
Top judicial officials said that he was aware of a plan which involved plans to murder the current president and his running partner, Alckmin, and to imprison and murder Alexandre de Moraes - the High Court judge who has been overseeing his judicial proceedings.
The conspiracy was thwarted because it failed to get the endorsement of the army and air force commanders. Lula was sworn in without issue on January 1st, 2023.
But a seven days after, on the eighth of January, numerous his backers stormed and vandalised government buildings in the federal district, Brazil's capital.
The security forces stepped in and around approximately 1,500 persons were detained.
The judges found that the protesters had been incited by the former president whose scheme, they said, was for the Brazilian military to take action, reestablish control and bring him back to power.
At the moment, the legal team called the over 27-year sentence extremely harsh.
He was also barred from running for public office until twenty-sixty - a decade minus two years after the end of his sentence.
The ex-leader called the trial a political persecution and said it was intended to stop him participating in the 2026 national vote.
