Columbia police say they've arrested a female suspect in an armed robbery at a sandwich shop last month.

37-year-old Diane Reese allegedly stole money from the cash register at Jersey Mike's in the 4700 block of Devine Street the evening of January 10th.

Police say surveillance video shows Reese pointing a gun at two workers, while making violent threats and demands for cash.

She also was heard yelling at one employee to get on the floor.

No one was harmed during the incident.

Reese is charged with armed robbery, kidnapping and possessing a weapon during a violent crime.
