Groton — The Dairy Queen on Fort Hill Road is closed, at least for the moment, after a small fire broke out in the back right corner of the building Wednesday morning, according to Poquonnock Bridge Deputy Chief Timothy Driscoll.

Driscoll said workers reported the fire at 42 Fort Hill Road about 8:20 a.m. On arrival, firefighters observed smoke coming from the base of the building. There was smoke inside, too.

Firefighters forced entry through the rear door and quickly extinguished the blaze. Driscoll said the area is a storage room.

Firefighters also exposed areas in the upper part of the building, where there also had been smoke, to ensure they knocked down the whole blaze.

Driscoll said a building official and members of the Ledge Light Health District were en route to check on the condition of the building and determine whether and when it could reopen.

Naval Submarine Base, Old Mystic, Mystic and City of Groton firefighters assisted with the call. Groton Ambulance also was on scene.

No one was injured in the fire and its cause and origin were under investigation.
