It was around 4:30 a.m. Sunday when the armed man walked into the Circle K on Lakeview Drive.
Officials said he displayed a gun as he demanded cash from the clerk, fleeing on foot once he got an undisclosed amount of cash. The clerk was alone at the time and wasn't hurt.
Maine State Police are now looking for the robber who was wearing blue jeans and a black hooded jacket. He also had a mask covering much of his face.
State police would like to hear from anyone who was at that Circle K between 4:30 a.m and 4:45 a.m. Sunday. You might have spotted something that could help lead to an arrest.
