The FBI has arrested a 59-year-old woman suspected of robbing an Arvest Bank in Lawton.
Agents say surveillance video captured Silvanna Warren robbing the bank at 5201 S.W. Lee Boulevard on June 6. They say she handed bank employees a note ordering them to stay calm and give her money. She left the bank with an undisclosed amount.
After Warren's image was released to the media, the FBI received multiple tips about her. Warren surrendered Monday to FBI agents at the federal courthouse in Lawton. She's been charged with robbery.
