Brazil's state-run oil company Petroleo Brasileiro SA extended a leave of absence for the head of its tanker and pipeline unit, Transpetro, for 30 more days according to a filing on Friday.
Transpetro President Sergio Machado stepped down temporarily on November 3 as police investigated a corruption scandal at the company that has delayed the release of audited earnings, implicated an array of major contractors and threatened to ensnare dozens of politicians.
