DENVER (AP) - Chipotle Mexican Grill Inc. says federal prosecutors are investigating the company for possible criminal violations of securities laws related to its hiring practices. The Department of Homeland Security's immigration enforcement unit is already probing the company for compliance with employee work authorization laws. The company said Friday that the Securities and Exchange Commission has issued a subpoena related to the matter. The company disclosed the latest probe, by the U.S. Attorney for the District of Columbia, in a SEC filing on Tuesday. The Denver company says it is cooperating with the investigations. In 2010, Chipotle fired about 450 Minnesota employees who couldn't prove they were eligible to work in the U.S. Federal officials then requested worker authorization documents for employees in Virginia and the nation's capital. That investigation continues.
