Suffolk County Crime Stoppers and Sixth Squad detectives are searching for three suspects in an armed robbery of a Holtsville convenience store earlier this month, police said Wednesday.

At about 8:48 p.m. March 12, a woman and two passengers drove to the service door of The Barn, at 1032 Portion Rd., police said.

They ordered a soda, and as the employee went to get it, a man wearing a ski mask and armed with a rifle got out of the car and demanded money.

The clerk complied, giving up an unspecified amount of cash. Then the man got back into the car and the three drove off, police said.

Police on Wednesday released photographs of the suspects taken from video surveillance at the store.

Anyone with information can call Crime Stoppers at 800-220-8477. All calls will be kept confidential.
