Houston’s Enron Building has fetched $55.5 million from a group of investors. The 50-story glass tower was sold via private auction on Tuesday, but the sale must still be approved by a New York federal bankruptcy court judge. The investor group is led by a Houston cardiologist, Dr. Antonio Pacifico.

Enron — which went bankrupt two years ago — leased the entire building from a consortium of banks that included J.P Morgan, one of Enron’s creditors. Proceeds from the sale of the building will be divided up among the lenders.

New York City-based Granite Partners represented the sellers.
