SUNDERLAND — A rock-paper-scissors scenario reportedly played out during an attempted robbery Friday at the Spirit Shoppe, where a suspect with a knife was bested by a package store clerk with a gun, according to a published report.

The would-be thief entered the liquor store at 295 Amherst Road with a large knife and demanded money. But when the female clerk pulled out a handgun, the male suspect fled the store without any cash, Sunderland Police Chief Jeffrey Gilbert told CBS 3 News, media partner of MassLive.com/The Republican.

That information could not immediately be verified with Gilbert, who was not expected to be back on duty until about 7 a.m. Monday, according to a Sunderland police dispatcher.

There were no reported injuries in the 2 p.m. Friday incident, which prompted authorities to launch a K-9 search for the suspect, who apparently still remains at large.

The suspect was described as a dark-haired, heavyset white man, about 5-foot-8 to 5-foot-10 inches tall, who was wearing a white knit mask, black Adidas windbreaker, gray or white pants, and black sneakers, according to The Recorder.

Sunderland police are asking anyone with information to call the department at (413) 665-7036. A 24-hour police emergency dispatch line may also be reached at (413) 625-8200.
