(CNN) Police are looking for three men suspected in a bold, daylight robbery at a New York jewelry store popular with rappers and other celebrities.

The thieves forced four employees at Avianne & Co. Jewelers into a back room on Sunday at about noon and then tied them up with zip ties and duct tape, according to the New York Police Department.

Closed-circuit video showed that at least two of the men were holding handguns as the employees lay on the floor.

Police said the men pretended to be customers before ransacking the store.

The men's faces are clearly visible in photos and video released by NYPD Crime Stoppers and there is a $2,500 reward for information leading to their arrest
