Delegado Protógenes Queiroz (PCdoB) presented a petition to install a Parliamentary Commission of Inquiry in the Chamber of Deputies to investigate privatizations carried out by the Fernando Henrique Cardoso administration (1995–2002).
Dantas was arrested twice by Protógenes Queiroz, police officer who investigated Daniel Dantas on Operation Satyagraha, in early July 2008, but each time released almost immediately.
According to Muniz, Téo is based on the federal police officer Protógenes Queiroz, responsible for the investigation and arrest of banker Daniel Dantas, accused of money laundering and convicted for attempting to bribe a federal police officer.
From 2004 to July 2008 Quieroz led Operation Satiagraha, a major operation into misuse of public funds, money laundering and corruption, leading to the arrest of the banker Daniel Dantas and several other prominent figures, including Celso Pitta, another former mayor of São Paulo.
