Five former employees of Bernard L. Madoff Investment Securities asked that prosecutors be ordered to turn over evidence they were lied to about the firm’s activities to help them fight charges they aided their boss’s fraud.

Annette Bongiorno, Joann Crupi, Daniel Bonventre, Jerome O’Hara and George Perez asked US District Judge Laura Taylor Swain to order the feds to turn over potentially favorable information, including statements from Frank DiPascali Jr., a key Madoff lieutenant who is cooperating with the government.

“We seek disclosure of any and all information suggesting that Madoff and others provided false explanations to customers, financial institutions, and regulators or employees in order to disguise the fact that BLMIS was not investing customer funds,” the defendants said in papers filed in federal court in Manhattan.
