Bolsonaro has been detained after authorities determined he posed a definite escape threat while under home confinement.
The one-time leader was found guilty of plotting a government overthrow in the ninth month and handed more than over two decades in incarceration, but he was staying under home detention pending court reviews.
Top Judicial Official Justice Moraes said the action to imprison the elderly politician was a preventative measure after recent developments came to light.
This included attempting to break his tracking device and a invitation to a supporters' gathering that could facilitate a chance to flee".
Judicial Records Show Escape Risks
In a filing authorising the custody, the magistrate said data from the unit overseeing Bolsonaro's house arrest suggested the ex-president's "intention to break the surveillance device to secure accomplishment in his getaway".
This, it said, would be made easier by the disorder caused by the gathering called by his son.
His child, Flávio, who serves as a legislator, called for a meeting of his backers near his father's house to take place on the weekend.
His son wrote on online platforms on last Friday: Will you battle for your nation, or watch it all from your smartphone there on your couch? I invite you to struggle with us."
He said the vigil would be so followers could "pray for his physical condition and for the restoration of democratic rule in our land."
Embassy Asylum Concerns
Part of the magistrate's determination was the possibility of his "relocation to diplomatic missions near the home, considering that the inquiries revealed a record of planning to seek refuge through a diplomatic representation", a declaration said.
The court filing emphasizes that the US embassy in the national capital, the capital city, is positioned around 8 miles from Bolsonaro's home.
Global Responses
His judicial problems have provoked anger from fellow populist conservative American leader Donald Trump, causing him to implement a 50% tariff on goods coming from Brazil.
Bolsonaro is being held in a national police facility in Brazil's capital city and will undergo a detention review on Sunday.
Latest Court Petitions
It was only on Friday that the his legal team asked the Supreme Court to authorize him to serve his whole jail sentence under home confinement, with digital surveillance.
They also requested that Bolsonaro be allowed to leave his home for medical treatment, saying he needed frequent medical attention for respiratory ailments and other illnesses.
Details of Guilty Verdict

High Court judges said that he knew of a plan which included plans to kill the current president and his running partner, Alckmin, and to detain and kill Alexandre de Moraes - the top judicial official who has been managing his judicial proceedings.
The conspiracy was prevented because it couldn't obtain the support of the armed forces officials. His successor was took office without incident on 1 January 2023.
But a seven days after, on the eighth of January, thousands of his followers attacked and damaged public facilities in the national capital, Brazil's capital.
