The 58-year-old Dreier is the founder and managing partner of the 250-lawyer firm Dreier LLP. The firm also has offices in Los Angeles, Santa Monica, Calif., Pittsburgh, Stamford, Conn. and Albany, N.Y.
A federal investigator said Dreier falsified financial statements in connection with the sale of more than $100 million in fictitious real estate notes.
Dreier was charged last week in Toronto with impersonation in connection with the attempted sale of $45 million of notes to a hedge fund.
Dreier was expected to appear in court in Manhattan later Monday. A message left with his lawyer was not immediately returned.
