This woman is the true definition of BADASS.

The attempted robbery happened at the Family Food Store on Detroit's west side on February 10th. Security footage shows the robber trying to snatch the woman's purse...until she starts to beat him with her cane.

In the words of one of the store's employees, "She fought back, and that's a good thing. She's from the old school."

If you have any information, please call the Detroit PD at (313) 596-5200.

Way to go, grandma!
