An FBI affidavit says Janetta Lenstrom, of Potter, had quit her job at another area bank the day before she robbed the Sidney Federal Savings & Loan last week.
A bank employee told investigators that she thought she recognized Lenstrom as the robber, who was wearing a stocking cap and sunglasses.
The affidavit says Lenstrom's husband was among the first officers on the scene but was pulled from the investigation. He later called her and asked her to meet him at a Sidney parking lot. The Sidney police chief arrested her when she arrived.
