MERIDEN - Police are shedding light on the planning that went into the intricate robbery of a Fairfield jewelry store last night.

Authorities say the suspects entered a Meriden apartment currently leased to Lenox Jewelers. There, they apparently tied up two hostages to be taken to the store to open it. One of these hostages, Sharbel Hanoosh, is the store's manager.

However, two visitors walked into the apartment at around the same time, prompting one of the robbers to stay behind and monitor them until the robbery was complete.

Investigators say the FBI is now involved to assist police.
