HDG Mansur is on the ropes, with numerous affiliated companies in bankruptcy, and its principal Harold Garrison himself sought personal bankruptcy last month. Worse Garrison and HDG Mansur are the subjects of a federal criminal investigation into whether they took $5.8 million from a client. Those plaintiffs, two Cayman Islands-based funds, aren’t alone in howling fraud. A year ago, KFH Capital Investment Co. and Kuwait Finance House Real Estate Co. filed a lawsuit in the United Kingdom accusing Garrison and HDG Mansur of misappropriating more than $11 million in connection with a failed development called Finzels Reach in Bristol, England. The court did not go along with a push by creditors to convert the bankruptcy of the HDG Mansur companies from Chapter 11 reorganizations to Chapter 7 liquidations.
