Brazilian police, investigating a massive kickback scheme at the Brazilian state-run oil company, Petrobras, are now looking closely at Peruvian President, Ollanta Humala, and a former Argentinian Transportation Minister, Ricardo Raul Jaime, according to an internal document obtained by The Associated Press.

The 44-page federal police report moves the sprawling corruption probe beyond Brazil’s borders, saying that investigators suspect Humala to have received $3m in bribes from the large Brazilian construction company Odebrecht in exchange for contracts in Peru.

The Peruvian President’s office denied the allegations and Humala summoned the Brazilian Ambassador in Lima “to express his rejection of such claims and demand official information.” Odebrecht in Peru also dismissed the accusations that it had been involved in the country’s corruption affair.
