Police say a female clerk foiled an attempted robbery on Saturday night when she pulled a gun on the masked intruder. They say the 24-year-old suspect robbed two other convenience stores of cash and cigarettes last week while wearing the blue Batman mask.

The woman fled into a car waiting outside after the clerk drew the weapon. Police also arrested a 23-year-old man who was in the car.

It’s unclear if the woman was armed during any of the robberies.

Police haven’t released their identities.
