Bolsonaro has been taken into custody after authorities found he posed a serious risk of fleeing while under home confinement.
The former head of state was convicted of plotting a armed takeover in September and sentenced more than over two decades in prison, but he continued under house arrest pending court reviews.
High Court Judge the presiding justice said the action to imprison the septuagenarian politician was a precautionary step after "new facts" were revealed.
This encompassed trying to remove his tracking device and a summons to a demonstration that could enable a chance to flee".
Court Filing Details Flight Fears
In a paperwork permitting 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 secure accomplishment in his flight.
This, it said, would be assisted by the confusion caused by the protest called by his son.
His son, Flávio, who works as a legislator, called for a gathering of his supporters near his father's house to take place on Saturday evening.
His son wrote on digital networks on last Friday: Will you battle for your country, or observe everything from your smartphone there on your settee? I invite you to struggle with us."
He said the gathering would be so supporters could "pray for his physical condition and for the restoration of democratic rule in our country."
Foreign Shelter Risks
Part of the judge's determination was the possibility of his move to diplomatic missions near the residence, considering that the investigations revealed a background of planning to seek refuge through a consular facility", a statement said.
The judicial paperwork underscores that the US embassy in the federal district, the capital city, is situated around 8 miles from his dwelling.
International Reactions
The former president's legal troubles have generated frustration from fellow populist conservative American leader President Trump, leading him to enact a half-rate duty on imports of Brazilian goods.
He is being detained in a national police facility in Brazil's capital city and will experience a custody hearing on the following day.
Latest Court Petitions
It was only on Friday that the former president's lawyers asked the High Court to authorize him to serve his whole jail sentence under home confinement, with digital surveillance.
They also petitioned that he be permitted to exit his dwelling for medical care, saying he demanded frequent medical attention for lung conditions and other illnesses.
Background on Conviction
Bolsonaro was found guilty of orchestrating a conspiracy aimed at retaining his authority after he failed to win the presidential race to his political opponent, Luiz Inácio Lula da Silva.
High Court judges said that he had knowledge of a plot which involved plans to murder Lula and his running partner, his vice-presidential candidate, and to arrest and execute the presiding judge - the top judicial official who has been overseeing the former president's case.
The conspiracy was stopped because it couldn't obtain the support of the military leaders. His successor was took office without issue on the first day of 2023.
But a seven days after, on the eighth of January, many his backers attacked and damaged official structures in the capital, Brazil's capital.
The police took action and around fifteen hundred individuals were detained.
The magistrates found that the rioters had been incited by the former president whose scheme, they said, was for the country's army to take action, restore order and reinstate his authority.
At the time, his attorneys called the decades-long sentence extremely harsh.
He was also prohibited from campaigning for office until 2060 - a decade minus two years after the completion of his term.
The ex-leader called the trial a political persecution and said it was intended to stop him competing in the next presidential race.
