SAO PAULO, Jan 12 (Reuters) - A judge in Rio de Janeiro convicted a former executive of Brazil's state-run oil firm Petrobras of fraud on a contract awarded to conglomerate Odebrecht SA and sentenced him to a maximum four years in jail on Tuesday.
Prosecutors said Jorge Zelada, former head of Petrobras' international division, helped scrap a competitive bidding process, resulting in Odebrecht winning a contract to analyze Petrobras' potential environmental liabilities abroad in 2010.
Zelada faces additional charges including corruption and money laundering in the southern city of Curitiba, the epicenter of Brazil's largest-ever corruption investigation.
Zelada's lawyer Ricardo de Moraes was not immediately available for comment but told Globo News he planned to appeal.
Prosecutors are unraveling a scheme they say involved engineering companies overcharging Petroleo Brasileiro SA, as the company is formally known, and used the excess funds to bribe executives and politicians. (Reporting by Caroline Stauffer; Editing by David Gregorio)
