Court Filing Details Escape Risks
In a document approving the arrest, Justice Moraes said data from the facility tracking his home detention suggested the former leader's "intention to break the surveillance device to guarantee victory in his getaway".
This, it said, would be assisted by the disorder caused by the demonstration called by his child.
His child, Flávio, who holds office as a senator, called for a gathering of his supporters near his father's house to take place on the weekend.
The senator wrote on online platforms on Friday: Do you plan to struggle for your homeland, or watch it all from your smartphone there on your couch? I call on you to battle with us."
He said the vigil would be so followers could offer prayers for his health and for the reestablishment of democratic governance in our land."
Foreign Shelter Risks
Part of Justice Moraes's ruling was the chance of the former president's move to embassies near the dwelling, considering that the inquiries revealed a background of arranging to ask for protection through a embassy office", a announcement said.
The court filing underscores that the US embassy in the capital, Brazil's capital, is situated around approximately 13 kilometers from his dwelling.
Worldwide Consequences

The former president is being kept in a federal law enforcement building in Brazil's capital city and will experience a imprisonment assessment on the next day.
Recent Judicial Appeals
It was only on Friday that the his legal team asked the Top Court to authorize him to serve his whole jail sentence under domestic detention, with tracking devices.
They also petitioned that Bolsonaro be permitted to leave his home for healthcare, saying he demanded frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
Bolsonaro was convicted of heading a conspiracy aimed at retaining his authority after he failed to win the national vote to his ideological adversary, Lula.
High Court judges said that he knew of a plan which included plans to murder Lula and his running partner, Alckmin, and to arrest and execute Alexandre de Moraes - the top judicial official who has been managing Bolsonaro's trial.
The plot was stopped because it failed to get the support of the military leaders. Lula was took office without incident on 1 January 2023.
But a following week, on the eighth of January, thousands of his backers attacked and damaged government buildings in the national capital, Brazil's capital.
The security forces intervened and around 1,500 people were taken into custody.
The magistrates found that the demonstrators had been provoked by the former president whose strategy, they said, was for the Brazilian military to step in, reestablish control and reinstate his authority.
At the period, the legal team called the decades-long sentence "absurdly excessive.
He was also prohibited from seeking elected position until twenty-sixty - eight years after the conclusion of his imprisonment.
The one-time head of state called the legal proceedings a political persecution and said it was intended to stop him competing in the 2026 national vote.
