Former Brazilian President Jair Bolsonaro was confined to house arrest after allegedly using social media in violation of a court order banning its use during his prosecution.

In a Monday ruling, Alexandre de Moraes, a Supreme Court justice and the judge responsible for Bolsonaro’s case, alleged that the former president had violated the terms of his restraining order by sharing posts through his sons’ and allies’ social media accounts. Moraes ordered authorities to seize his cellphone and confine him to house arrest, limiting visits to his family and allies.
