Businessman Fabiano Zettel will remain in pretrial detention as part of an investigation into suspected financial fraud involving Banco Master in Brazil. On November 5, Edson Fachin, chief justice of the Federal Supreme Court (STF), rejected requests for his release and for house arrest submitted by his defense.

Fachin said detention was necessary to protect the investigation, ensure the enforcement of criminal law and prevent risks to public order. The Office of the Prosecutor General also opposed his release. According to the Federal Police, Zettel allegedly acted as a financial operator for former banker Daniel Vorcaro, his brother-in-law, and helped facilitate payments.

The defense requested house arrest on humanitarian grounds, citing the health of Zettel’s wife and the recent birth of their twins. Fachin concluded that the absence of a family support network had not been demonstrated. The lawyers also said the businessman’s activities were unrelated to the bank’s management. The decision does not constitute a conviction or a final judgment.
