A federal judge in New York has dismissed for the third time a $10 million securities fraud suit against Chinese firm DeHeng Law Offices and one of its former partners.

The case stemmed from a 2008 deal in which the plaintiffs, several U.S. investment funds, attempted to acquire a Chinese distributor of hospital equipment. The plaintiffs claimed their investment of around $10 million was stolen by a man associated with and possibly married to former DeHeng partner Helen Lv (pronounced Lü).
