The robber fled the station around 1:30 a.m. with an undisclosed amount of cash and was last seen running east on South Avenue (Route 123) toward County Square, police said. A sweatshirt and pants believed to have been worn by the robber were found on Thacher Street (Route 123) and Rathbun Willard Drive, about a quarter mile from the robbery scene. Detective Russell Castro said the man entered the 24-hour gas station and asked the clerk for a pack of cigarettes before handing her a $10 bill and demanding cash. `` He threatened to shoot the clerk if she didn't give him the cash,'' Castro said. No weapon was shown. The man was described as a white male, about 5-feet 5-inches or 5-feet 6-inches tall. He wore a dark hooded sweatshirt with a logo, black pants and white sneakers. Anyone with any information is urged to call police at 508-222-1259. The robbery is under investigation by Castro and Officer Craig Fonseca.
