The call came in around 1:45 am Tuesday. A clerk at the convenience store told police that the robber came in and threatened them with a weapon, although they never actually saw the weapon.
The robber demanded cash, then took off on foot Northbound along Route 2. Police say less than $500 was stolen.
The robber is described as 5 foot, 11 inches tall.
He was wearing a gray hooded sweatshirt and an orange knit hat that he pulled low over his eyes at the time of the hold up.
Anyone with information is asked to call police.
