Dana Campbell of Arlington appeared Friday in federal court in Fort Worth. She's held pending a detention hearing next week.
Campbell was arrested Monday following an Arlington traffic stop. Police determined she faced several misdemeanor traffic warrants when they noticed a black hooded jacket in her vehicle.
Prosecutors say police located notes saying "This is a robbery" and "This is a robbery. I don't want to hurt anyone."
Officers also confiscated a ledger with dates and addresses of banks in the Dallas-Fort Worth area. All had been robbed since November by a person wearing a hoodie.
Information wasn't immediately available on an attorney for Campbell.
