SACRAMENTO, Calif. (AP) — California's attorney general is conducting a criminal investigation into whether employees at San Francisco-based Wells Fargo bank committed false impersonation and identity theft in the sales practices scandal that rocked the bank and cost its CEO his job, documents released Wednesday show. A search warrant and supporting affidavit released by the state Department of Justice show that agents sought evidence related to allegations that bank employees created up to 2 million bank and credit card accounts without customers' approval in order to meet sales goals. The warrant, first reported by the Los Angeles Times, was served Oct.
