Police said damage to the store was contained to the rear of the building, and consisted of insulation and sheetrock damage. A hole was cut into the roof, police said, to ventilate the building.

The new store, the first Trader Joe's in Somerset County, was scheduled to officially open Friday in the former Golfsmith at the Promenade. There is no word yet on whether that can still happen, but Trader Joe's is expected to make an announcement soon.

Responding to the scene to aid with the investigation were Bound Brook Fire Department, Green Knoll Fire Department, Manville Fire Department, Robert Wood Johnson Ambulance, Bridgewater Township Health Department and Bridgewater Township Fire Official.
