Zurich - Switzerland's attorney general said on Wednesday he has uncovered over 300 accounts at more than 30 Swiss banks that he believes are linked to money laundering and corruption at Brazil's state-run oil firm Petroleo Brasileiro SA.
The scandal, involving billions of dollars of allegedly misappropriated funds, has reached the highest levels of power in Brazil, where about 1 million demonstrators turned out over the weekend to vent their anger and call for the impeachment of President Dilma Rousseff, who was chairperson of Petrobras' board when much of the alleged graft occurred.
Investigators in the alpine nation said they are looking into eight Brazilians in connection with their probe, as well as other, as yet unidentified people after it found evidence that senior executives at Petrobras and suppliers used accounts at more than 30 Swiss banks to launder money.
