RIO DE JANEIRO, Feb 10 (Reuters) - A Brazilian federal court suspended on Friday the $5.2 billion sale of state-controlled Petróleo Brasileiro SA's natural gas pipeline unit to a group of investors led by Canada's Brookfield Asset Management Inc BAMa.TO .
In a document seen by Reuters, the Sergipe state-based court ruled the transaction, which was to be closed within weeks, be halted because of discrepancies with the way Petrobras PETR4.SA proceeded with the sale.
