In July 2026 the Federal Police seized spreadsheets from alleged bicheiro Adilson Oliveira Coutinho Filho (Adilsinho) in Cabo Frio, revealing a R$ 29.3 million parallel‑accounting scheme linked to political candidates. In early August a separate crackdown stopped a fraudster in São Paulo from withdrawing INSS benefits with forged documents and dismantled a scheme that siphoned more than R$ 8 million from the Serpro corporate health plan through fabricated medical reports.

On 6 August 2026 the police launched Operation Heritage, authorized by Supreme Court minister Flávio Dino, to probe the alleged diversion of over R$ 308 million from a 2024 settlement between Mato Grosso and telecom operator Oi. Twenty‑five search and seizure warrants were executed in Mato Grosso, São Paulo, Rondônia and Ceará, blocking assets worth up to R$ 316 million, seizing passports and lifting bank‑secrecy orders. Investigators say a network of cascade investment funds and shell companies—including Banco Master, Royal Capital and Lotte Word—was used to launder the money. A prosecutors’ request to suspend several officials was denied, with Dino leaving open the possibility of administrative action, and further judicial measures are ongoing.
