It happened on August 20, at Washington Lane Discount Store on the 1900 block of Washington Lane.
Authorities say one of the suspects got into the store through a broken security gate and window.
Once inside, police say the man went behind the counter and took a number of lottery tickets, passing them to a second suspect who acted as a lookout.
Both suspects fled on foot in an unknown direction.
