(Reuters) - Private-equity firm Blackstone Group LP <BX.N> is no longer looking at buying a $5 billion stake in Energy Transfer Partners <ETP.N>, a source familiar with the matter confirmed on Monday.


In December, Blackstone was said to be looking at a stake in ETP, the company building the controversial Dakota Access Pipeline.


ETP shares fell 2.4 percent on Monday to close at $36.53 a share after the news, first reported by Bloomberg.


ETP announced a private placement of shares with its parent Energy Transfer Equity LP <ETE.N> on Monday, which will garner ETP proceeds of $568 million, in exchange for about 15.8 million common shares of ETP. Shares of the parent company lost 4.7 percent on Monday.
