CORRECTED-Petrobras, seeking lost money, wants bigger role in corruption probe
(Corrects headline and first paragraph to show that Petrobras wants a bigger role for itself in probe, not a bigger role for prosecutors)
RIO DE JANEIRO, April 27 (Reuters) - Brazil's Petrobras said on Monday it has asked prosecutors to allow it to assist more closely with investigations into a broad corruption scheme focused on the state-run oil firm.
The move, which fits into the oil company's position that it was the victim and not the perpetrator of any corruption scheme, could help it retrieve money lost through criminal activity, Petrobras said in a securities filing.
Prosecutors say executives at Petroleo Brasileiro SA, as the company is formally known, systematically over-charged construction companies, with the excess being used to pay political bribes. (Reporting by Stephen Eisenhammer; Editing by Leslie Adler)
