Groton — A fire at the Super 8 Hotel in Groton Monday afternoon led to its evacuation and water damage to some of the units.

City of Groton Fire Chief Robert Tompkins said the city’s building official was assessing whether any of the hotel tenants, some of whom live at the hotel, would be displaced. The Red Cross was at the hotel located at 173 Route 12 in the event people needed assistance.

The fire appears to have started in a third-floor unit that was unoccupied and being used for storage. Tompkins said the fire, reported shortly after 3 p.m., set off the sprinkler system in the room which extinguished the fire but also led to water streaming into the floors below. Water was leaking into the first floor lobby through the drop ceiling. Tomkins said about eight units were impacted.

The cause of the fire is under investigation. Firefighters were expected to remain at the scene as part of a fire watch until the building's sprinkler system is recharged.
