An early-morning apartment fire required evacuation of a three-story apartment building at 8 Kessler Farm Drive in Nashua.
Arriving crews reported smoke showing from the three-story Boulder Park Apartment building at about 7:30 a.m.
Several residents were still inside and needed to be evacuated by fire personnel.
Crews stretched hose lines to the second floor and extinguished a fire in the bathroom. Fire was confined to the bathroom area.
Due to heavy smoke conditions fire crews assisted occupants out of building and searched all apartments to make sure nobody was trapped inside.
The fire originated in a bathroom at Unit 635, fire officials said.
The fire is under investigation by the Nashua Fire Marshal's office.
