BRASILIA, Sept 5 (Reuters) - Brazilian police launched an investigation of fraud at state-run companies' pension funds on Monday, as a judge ordered dozens of senior financiers and executives away from their firms, including the chief executive of the world's biggest beef exporter.
Police carried out five arrests, more than two dozen interrogations and over 100 search warrants, seizing jewels, luxury vehicles, artwork and an airplane in an asset freeze to cover up to 8 billion reais ($2.5 billion) in alleged damages.
The federal judge overseeing the case, Vallisney De Souza Oliveira, ordered the chief executive of meat packer JBS SA and 39 others under investigation to suspend their corporate roles, avoid all capital market activity and forfeit their passports in order to avoid jail.
JBS shares fell 10 percent, the biggest drop in six months, at the prospect of billionaire brothers Wesley and Joesley Batista, who run JBS and their family's holding company J&F Investimentos, respectively, from serving at the group's firms.
The probe of the pension funds is the latest in a string of investigations into corruption at the vast overlap of Brazilian business and politics, rattling Latin America's largest economy and feeding political instability.
The four pension funds under investigation, which controlled about 280 billion reais in assets last year, have been an important source of investment in Brazil's credit-starved economy, but political connections at the state-run firms have raised questions about influence in their decisions.
The pension funds caught up in Monday's investigation are those of state-run banks Caixa Economica Federal and Banco do Brasil, postal service Correios and oil giant Petroleo Brasileiro SA, the company known as Petrobras which has been ground zero of the graft investigations roiling the nation.
Yet police said their investigation focused on losses to pensioners from reckless or fraudulent investments throughout the Brazilian economy.
Other executives mentioned in the judge's search and seizure order included the chief executive of wood pulp maker Eldorado Brasil Celulose SA, also controlled by the Batista family, Jose Carlos Grubisich; and Denise Pavarina, the head of the asset management unit at lender Banco Bradesco SA. Neither executive was ordered to step away from their companies.
Press representatives for J&F and Eldorado said their executives were collaborating with the investigation. JBS referred comment to J&F.
Bradesco said its asset management units "follow the regulations in funds under management and rules by regulators" and that the bank is cooperating with authorities.
Pension funds Previ, Petros and Funcef said they were collaborating with police. Petros added that the investigation involved decisions made in 2011. Postalis did not immediately respond to a request for comment
Caixa, Bradesco, Banco Santander Brasil and fund manager Rio Bravo Investimentos Ltda confirmed that their asset management units were also targeted by the operation.
In a statement, Caixa said the bank already had an internal investigation about "possible irregularities" involving the employees pension fund's investments.
Santander Brasil said the federal police asked for documents related to investments by the pension funds in the rig lessor Sete Brasil, which is under bankruptcy protection, and in a fund called Global Equity.
Asset manager Rio Bravo, the target of acquisition by China's Fosun International Ltd, said the fund has always managed pension funds investments "with ethics, honesty and compliance with the laws."
