John Senesac, 40, of 1503 Portland Colbalt Road, is accused of robbing the gas station at 1633 Portland Colbalt Road at knifepoint just after 4:30 p.m.
After the robbery, the clerk followed the robber from the store and watched him turn onto Brickyard Road, according to police.

Police said they found a knife, the clothing used in the robbery and the stolen cash in Senesac’s apartment.
Officers also identified Senesac through surveillance video, police said.
He was charged with a parole violation, robbery, threatening and larceny.
Senesac was held on $100,000 bond and is due in court on Friday.
