A man wearing a mask and brandishing a gun entered Lloyd's Chevron near the Flatwoods exit of Interstate 79 about 5 a.m..

The man demanded money, then fled in a white sedan, heading north on Interstate 79.

Police responded and searched the interstate with no results.

In addition to the mask, the suspect was wearing a black sweatshirt, a green jacket, dark-colored pants and white shoes.

The clerk, the only other person in the store, was not injured.
