A man saved three children and a dog from a burning apartment building in Waterville on Tuesday.

Aaron Brunelle, a tenant in a first-floor apartment in a Morrill Avenue building, saw the fire about 2 p.m. and went upstairs to warn the other tenants, according to the Waterville Fire Department.

In a third-floor apartment, Brunelle found three children and a dog, and he guided them to safety down a long stairway where they were met by firefighters, according to the department.

“If it weren’t for Mr. Brunelle entering the structure and assisting the children to safety, the outcome could have been far worse,” Waterville Fire Chief Shawn Esler said.

Esler said he will recommend to the city manager that Brunelle be recognized by the city and fire department for his heroic act that “likely saved these children’s lives.”

No one was hurt in the fire, but multiple cats died.

Ten people have been displaced by the fire, and the Red Cross is assisting them with housing.

High winds and rapid-fire growth made it more difficult to extinguishing the fire.

The cause of the fire is under investigation, but officials said the fire appears to have started on the outside of the building.
