Tide Natural Gas Storage I LP, which paid $515 million for natural gas assets from a subsidiary of Bahrain's bankrupt Arcapita Bank BSC, asked a New York bankruptcy court Monday to appoint a trustee of the subsidiary's bankruptcy because of conflicts of interest. Tide asked to convert Arcapita subsidiary Falcon Gas Storage Co. Inc.'s bankruptcy from Chapter 11 to Chapter 7 and for the court to appoint a trustee because Arcapita reorganization's plan will give the Bahraini bank and its creditors too much power.
