She may be 72-years-old and a great grandmother but she certainly isn’t afraid to use a gun. Police in Columbia, Tennessee believe Flo Armstreet may have stopped the Dollar General Store from being robbed by two men.

Armstreet said she pointed a pistol at the men who got out of a car behind her Summertown flea market and ordered them to put their hands on the vehicle where she could see them. Neighbors called police and arrived to help Armstreet on Sunday night.

Lawrence County Police arrested two 21-year-old men – Travis G. Carter of Spring Hill and Freddie Currie II of Columbia. They are charged with attempted aggravated robbery, aggravated criminal trespass, marijuana possession and unlawful possession of a weapon.

Armstreet said she would have shot them if necessary.
