A Lexington man was charged Wednesday with robbing a woman at a discount store on Richmond Road.
Lexington police spokeswoman Sherelle Roberts said the woman was shopping Monday at the Family Dollar at 2051 Richmond Road.
Roberts said Christopher Scott McDonald, 19, followed the woman out of the store, brandished a knife and ran off with her wallet.
Police have not released the victim's name.
Officers were able to identify McDonald through surveillance video, and they located and arrested him after receiving a tip that he had been seen Wednesday near the Eastland Shopping Center.
McDonald is charged with first-degree robbery and was taken to the Fayette County jail.
