Diomar Tadeu Dantas de Farias, co-owner of the Brazilian sports betting company Pixbet, was arrested on Thursday morning (Sept. 17) in the second phase of Operação Arena, an investigation run by the Federal Police (PF), Brazil's federal investigative force. According to G1, officers found him at a beach house in Jacumã, on the southern coast of Paraíba state, and he was to be taken to Campina Grande, the city where the company is headquartered.
Beyond the preventive arrest, the PF served five search-and-seizure warrants and asset-freeze measures in Campina Grande and João Pessoa, Folha de S.Paulo reports. Jornal da Paraíba says the arrest warrant was meant to be served in Campina Grande, but Tadeu Dantas was not there. It is the first arrest since the operation was launched in August by the PF, the Paraíba state prosecutors' office and the Federal Revenue Service.
Outlets diverge on who was actually arrested. Folha reported the detainee was Ernildo Júnior de Farias Santos, described by the paper as Pixbet's owner. G1 and Jornal da Paraíba report that the PF confirmed only the identity of Tadeu Dantas, Ernildo's cousin and a partner in the business. Ernildo was targeted in the first phase in August, when police stopped him on a highway outside Campina Grande and seized his car and phone. As of publication, no outlet had reached Tadeu Dantas's lawyers.
How the alleged scheme worked
Arena investigates money laundering and evasão de divisas, the crime of sending money abroad without declaring it. According to investigators, the mechanics were those of an accounting laundromat: bettors' money left Brazil for a shell company registered in Curaçao, then returned as payment for services that, in the PF's account, never existed, backed by invoices that gave the funds a legal appearance.
Folha adds another layer: the money was converted into stablecoins, cryptocurrencies pegged to the dollar that move across borders without passing through a bank, and was also exchanged for dollars at currency houses before landing in accounts in tax havens. The paper reports the scheme may also have financed Pixbet's licensing in Brazil. In the first phase, a court ordered banking secrecy lifted and authorized freezing up to R$ 1.1 billion in assets, with warrants served in five states (19, per G1; Folha counted 17).
What we still do not know
A preventive arrest in Brazil is a pre-trial measure. The PF has not detailed the evidence behind the detention or named the targets of the other five warrants, and Tadeu Dantas's defense has not spoken. The asset freeze is provisional and can be reversed in court. The split between outlets over the detainee's identity shows the picture is still moving.
The case reaches football and bettors' wallets. Pixbet sponsored Flamengo under a deal set at R$ 125 million per season, terminated in August 2025 after payment delays, and Corinthians, which ended the partnership in 2024 and was then billed a R$ 20 million penalty by the company. Betting firms live on volume, and sponsoring big clubs is the cheapest shop window for signing up bettors, which explains the contracts and assets such as Serra Branca Esporte Clube and the Arena Vaquejada Pixbet, in Gurinhém. Since July, a Paraíba court has suspended the company's platforms nationwide for failing to keep minors out. Watch whether prosecutors file formal charges, whether the suspension holds, and what happens to customers' balances as the operation advances.
