SAO PAULO, Jan 8 (Reuters) - Brazil’s top prosecutor has found evidence that a bribery scheme involving local engineering firms and the state oil company extended to pension funds and a workers’ fund, benefiting the ruling Workers’ Party and allies, newspaper Folha de S. Paulo reported on Friday.
The paper said the potential new front in Brazil’s largest-ever corruption investigation was based on a slew of text messages leaked to the local press on Thursday from Leo Pinheiro, the convicted former head of engineering firm OAS.
“According to what can be inferred from the messages, there were debentures issued by the companies acquired by banks ... or by pension funds where there is political interference,” top Brazilian prosecutor Rodrigo Janot wrote in documents seen by Folha.
Janot said the messages indicated OAS might have paid bribes to politicians, including House Speaker Eduardo Cunha, or made official campaign donations to political parties in exchange for the financial transactions that raised funds, according to Folha.
The leaked texts, sharply criticized by Brazil’s justice minister on Thursday, could lead prosecutors to formally investigate several members of President Dilma Rousseff’s cabinet, creating more headaches for the unpopular leader as she fights unrelated impeachment charges and a recession.
Dozens of engineering firms are being investigated for price-fixing contracts and overcharging state-run oil company Petroleo Brasileiro SA to gain funds used to bribe politicians. Pinheiro has been sentenced to 16 years in jail for money laundering and corruption.
Newspaper Valor Economico also reported on Friday that plea bargain testimony from former Petrobras executive Nestor Cervero showed Rousseff’s chief of staff, Jaques Wagner, received large sums of money diverted from Petrobras to run his 2006 campaign for governor of Bahia state.
OAS said in a statement that it would not comment on the case.
Wagner said in a statement that he would cooperate with authorities but would not comment on Cervero’s testimony because he did not know its full content or real context.
A spokeswoman for the federal prosecutor’s office did not have an immediate comment on the reports. (Reporting by Caroline Stauffer; Editing by Lisa Von Ahn and Sandra Maler)
