The robbery of a Lake Ronkonkoma drugstore Thursday evening may be connected to a series of pattern robberies -- believed to be the work of one man -- pulled off in the past two weeks across Suffolk County, police said.

In the latest robbery, the suspect entered CVS, 729 Portion Rd., at about 5:20 p.m. "demanded money and displayed what appeared to be a handgun," Suffolk police said Friday in a news release. The suspect fled with an undisclosed amount of money.

The robbery spree began Oct. 26, and seven of the targets were gas stations, police said. Investigators believe a robbery at a Jamba Juice bar in Stony Brook also is part of the string.

As part of the pattern, the robber typically enters an establishment, pretends to purchase an item and then, when the employee opens the cash register, produces the handgun -- and demands cash, police said.

The suspect then flees, police said, possibly to a waiting vehicle nearby the location.

The gas stations robbed in the spree were in Eastport, Calverton, Mastic, North Babylon, St. James, Dix Hills and Bohemia. No one has been injured in the robberies.

The suspect is described as being in his late 20s or early 30s, between 5-foot-10 and 6-foot-2, with a thin to medium build. He usually wears a dark-color or gray hooded sweatshirt, police said.

Police ask anyone with information about the robberies to call Crime Stoppers at 800-220-TIPS. All calls will remain confidential.
