The U.S. Department of Justice has subpoenaed a high-profile whistleblower in its criminal investigation into Wells Fargo & Co.'s opening of accounts without customer permission.
U.S. prosecutors in San Francisco have asked Wells Fargo banker Yesenia Guitron, who lost a private lawsuit against the fourth-largest lender, to testify before a grand jury in San Francisco on Tuesday, according to a subpoena dated Dec. 12, which was seen by Reuters.
A Wells Fargo spokesman declined to comment.
Guitron is among at least five Wells Fargo employees who sued the bank or filed complaints with regulators alleging that they were fired after reporting the opening of customer accounts without their permission, according to a Reuters review of lawsuits and complaints to the U.S. Labor Department.
The suits and complaints, filed between 2010 and 2014, raise questions about how early Wells Fargo knew about such allegations and how it handled them.
San Francisco-based Wells Fargo reached a settlement with U.S. regulators and the Los Angeles city attorney in September.
The Justice Department subpoena directs Guitron to bring all documents related to her employment at Wells, including any related to sales practices, discipline "or other form of retaliation taken against you by Wells Fargo or Wells Fargo employees."
Guitron and her lawyer were not immediately available for comment. A spokesman for the U.S. attorney for the Northern District of California, which issued the subpoena, declined to comment.
