The Exxon gas station was robbed by a man with a knife early Tuesday morning.
A man holding what looked like a kitchen knife walked into the gas station at the intersection of Route 924 and Singer Road in Abingdon shortly after midnight Monday. He demanded cash from the clerk, who handed over an undisclosed amount of cash, then ran out of the store and down Singer Road, Maryland State Police TFC Michael Bonczewski said Thursday.
The robber is described as a white man who was wearing black pants and a gray hooded sweat shirt with the hood covering most of his face.
Troopers used a police dog to track the robber down Singer Road but he wasn't found, Bonczewski said.
The clerk was not hurt.
Anyone with information on the robbery is asked to call Bonczewski at the Maryland State Police Bel Air Barrack, 410-879-2101.
