Brazilian Supreme Court Justice Alexandre de Moraes has upheld the preventive detention of Rafael Martins de Oliveira, known as "Kid Preto," who is accused of involvement in a plot to assassinate President Luiz Inácio Lula da Silva and other authorities, including Justice Moraes himself. The decision came after the defense requested to replace the preventive detention with precautionary measures, which Moraes denied. Rafael Martins de Oliveira, a lieutenant colonel in the Brazilian Army, is also linked to an alleged coup attempt. Additionally, Brazilian police have arrested a criminal involved in an attempted kidnapping of former Minister of Justice Sérgio Moro.
