It was not just the allegation of a scheme to take illegal payments from shipowners that led Brazilian Federal Police to seek the arrest of former Petrobras chartering executive Dalmo Monteiro Silva.

They also want to know about his daughter’s 2009 honeymoon in Greece, which prosecutors suspect was paid for by the director of Onassis group’s Olympic Agencies.

That was the same year that affiliate owner Olympic Shipping & Management began a chartering relationship with government-controlled Petrobras.
