Bolsonaro has been arrested after authorities determined he posed a definite escape threat while under house arrest.
The one-time leader was found guilty of plotting a armed takeover in the ninth month and given more than a 27-year term in prison, but he was staying under confinement pending legal challenges.
Brazilian Supreme Court Justice Alexandre de Moraes said the move to detain the elderly politician was a precautionary step after fresh information emerged.
This encompassed seeking to disable his electronic bracelet and a invitation to a public vigil that could enable a possible escape.
Judicial Records Show Escape Concerns
In a paperwork permitting the custody, the judge said information from the centre monitoring his home detention suggested the former leader's aim to disable the electronic ankle bracelet to ensure success in his escape.
This, it said, would be made easier by the chaos caused by the demonstration called by his offspring.
His son, Flávio, who serves as a congressional representative, called for a gathering of his followers near the former president's residence to take place on the weekend.
His son wrote on social media on last Friday: "Are you going to fight for your country, or see it all from your smartphone there on your settee? I urge you to battle with us."
He said the gathering would be so backers could offer prayers for his health and for the return of democracy in our country."
Diplomatic Refuge Fears
Part of the judge's determination was the potential of Bolsonaro's "relocation to foreign missions near the residence, considering that the probes revealed a history of organizing to ask for protection through a embassy office", a statement said.
The judicial paperwork underscores that the American diplomatic mission in the federal district, the capital city, is positioned around approximately 13 kilometers from his dwelling.
Worldwide Consequences
Bolsonaro's legal woes have drawn the ire of fellow conservative nationalist US President President Trump, causing him to enact a fifty percent tax on goods coming from Brazil.
He is being held in a Federal Police station in the capital and will have a custody hearing on the next day.
Latest Court Petitions
It was only on the previous day that the ex-leader's attorneys asked the High Court to permit him to fulfill his full incarceration period under house arrest, with electronic monitoring.
They also asked that he be authorized to exit his dwelling for medical treatment, saying he required regular treatment for respiratory ailments and other illnesses.
Details of Guilty Verdict
He was determined responsible of heading a scheme aimed at retaining his authority after he lost the 2022 election to his political opponent, Luiz Inácio Lula da Silva.
Top judicial officials said that he knew of a scheme which involved plans to murder his opponent and his VP candidate, Alckmin, and to imprison and murder Alexandre de Moraes - the top judicial official who has been overseeing the former president's case.
The plot was prevented because it failed to get the support of the army and air force commanders. His successor was inaugurated without issue on the first day of 2023.
But a week later, on 8 January, numerous Bolsonaro supporters stormed and vandalised official structures in the national capital, the capital city.
The security forces stepped in and around approximately 1,500 persons were arrested.
The judges found that the protesters had been provoked by the former president whose plan, they said, was for the country's army to step in, reestablish control and bring him back to power.
At the period, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also banned from running for public office until 2060 - eight years later after the end of his sentence.
The former president called the trial a "witch hunt and said it was intended to stop him participating in the 2026 presidential election.
