The founder of consulting firm AlixPartners, Jay Alix, filed a complaint against rival McKinsey & Co. in Manhattan federal court Wednesday, charging the international consulting behemoth with racketeering conspiracies to conceal conflicts of interest in corporate bankruptcy cases.

The 150-page complaint filed in the U.S. District Court for the Southern District of New York alleged that McKinsey, its affiliates, and top officials operated a criminal enterprise, engaged in bankruptcy fraud, as well as mail and wire fraud, to keep tens of millions in bankruptcy fees flowing.
