Police in Lisbon and nearby cities are looking for a man they say wore a mask and brandished a knife during the heist at the 634 Lisbon St. store.

Police said the suspect walked into the Big Apple store at about 11:30 p.m. Wednesday, pulled out a knife and demanded cash from the clerk.

Police said the suspect left the store on foot with an undisclosed amount of cash. No one was hurt.

The suspect was described as a white male possibly in his early 20s, approximately 5-foot-6-inches to 5-foot-8-inches tall, weighing between 150 and 160 pounds. He was wearing a black hooded sweatshirt and blue jeans and his face was covered by a gray mask.

Police on Thursday released footage from a store surveillance camera in hopes of generating leads. The images show the suspect wearing a horror-movie style mask beneath the dark hood. Anyone with information is asked to call Lisbon police at 353-2500.
