A man with a gun tried to rob Green Oak Center gas station early today, police say.

A white male armed with a shotgun on a sling went into the gas station, 243 W. Main St., about 4 a.m. and demanded money from the register, said Sgt. Mike Wilbanks at the Farmington Police Department.

The employee refused to give him the money. He left and fled west toward Fayetteville, Wilbanks said.

He was driving a half-ton, dark-colored Chevrolet truck, Wilbanks said.

The suspect is a white male, approximately six feet tall, and weighs about 170 to 180 pounds, Wilbanks said. The suspect was dressed in all black, and wearing a hooded jacket and had a white bandana covering his face, Wilbanks said.
