TULSA, Oklahoma - A woman who police believe may be connected to a string of robberies last weekend hit the same Fiesta Mart early Tuesday morning.

Police were called out to the store at 11th and New Haven in Tulsa just after midnight.

Police say the heavy-set woman got away with a small amount of cash. The clerk told police the woman was armed with a bb gun.

K-9 units were able to track her route but lost her scent just a few blocks away where police believe she left in a car.

Tulsa Police believe the woman is the same person who attempted to rob the same store last Sunday and successfully robbed another Fiesta Mart and a McDonald's the same night.

Witnesses told police she fired a handgun into the ground during the McDonald's robbery on April 22, 2012.

If you know anything that can help police, you're asked to call Crime Stoppers at 918-596-COPS.
