Former Petrobras Director Says Graft Scheme Widespread In Brazil

BRASILIA, Dec 2 (Reuters) - A former Petrobras executive at the center of an alleged multibillion-dollar graft scheme involving the state-run oil company said on Tuesday that similar bribery and kickback schemes are prevalent in many Brazilian public-infrastructure projects.

The March arrest of the executive, Paulo Roberto Costa, helped uncover a scheme that allegedly used inflated Petrobras contracts for refineries and other projects to funnel money to politicians through leading construction companies.

At a Congressional hearing on Tuesday, Costa said the practice extends beyond Petroleo Brasileiro SA, as Petrobras is formally known.

"What has been reported occurring at Petrobras happens all over Brazil in contracts for roads, railways, ports, airports, hydroelectric dams," Costa said.

The case is sharpening Brazilian political divisions only weeks after President Dilma Rousseff won re-election in the country's closest vote in decades. Rousseff, chairwoman of Petrobras' board of directors from 2003 to 2010 when many of the alleged bribes and kickbacks happened, has denied involvement in the corruption scheme.

Political parties have dominated all high-level appointments at Petrobras, including his own, for decades, Costa said.

Last month, prosecutors began probing other state-run companies after dozens of construction and engineering firm executives were arrested Nov. 14 in relation to the Petrobras case.
