A Mobile woman is behind bars charged in Wednesday's robbery of a Compass Bank on Bel Air Boulevard. Authorities said 55-year-old Faith Sullivan used a taxi cab to take her to and from the bank.

Police said the robbery occurred at about 9 a.m.

Sullivan allegedly walked into the bank and demanded money from a teller and was given undetermined amount of cash. She was arrested a short time later at a motel on the I-65 Beltline.
