Oxford Police Chief John Tibbetts said the robber, wearing a gray hooded sweatshirt, sunglasses and a bandana across his face, entered Lampron's Lil Mart on Route 26 around 10 p.m. Thursday. The man, believed to be in his mid 20s, approached the counter and told the female clerk, "This is a robbery. Give me the money," Tibbetts said. The clerk, thinking that she saw a soda bottle in the man's sweatshirt pocket, responded by asking the robbery to show her his gun, Tibbetts said. The man then turned around and left the store empty-handed, he said.
