The Securities and Exchange Commission filed an emergency action charging Robert C. Morgan, a New York residential and commercial real estate developer, and two of his entities, Morgan Mezzanine Fund Manager LLC and Morgan Acquisitions, LLC, with fraud for siphoning and misusing investor funds. In its action, filed Wednesday, the SEC seeks an asset freeze and other emergency relief. The SEC's complaint alleges Morgan financed his development projects in different ways, including through sales of securities directly to more than 200 retail investors, many of whom invested through their retirement accounts.
