Police said they are looking for one of two men who threatened to shoot loss prevention officers who caught them stealing clothing from Saks Fifth Avenue at the Walt Whitman Shops in Huntington.
The pair got away in the robbery last fall, though one was caught a month later.
Suffolk County police have released a video surveillance photo of the second suspect, hoping the public has information that will help investigators find and arrest him.
The robbery occurred on Nov. 20, police said.
On Dec. 18, police said, they arrested Sequan Watts, 20, of Brooklyn, charging him with first-degree robbery, second-degree robbery and criminal possession of an anti-security item. But they have been unable to locate his partner.
Police asked anyone with information about the man in the surveillance photo to call Crime Stoppers at 800-220-8477 or to text SCPD at CRIMES (274637). Tipsters can also submit information at tipsubmit.com. All calls and messages are confidential, and tipsters are eligible for a cash reward of up to $5,000 for any information leading to an arrest in the case.
