Portland firefighters are on the scene of an all-hands fire at 73 Lawn Ave.

Firefighters were called to the two-story, two-family house, in a neighborhood off Stevens Avenue, at about 9 p.m. when a passerby spotted smoke and flames.

Firefighters worked to vent the roof and pull shingles off the walls, while others brought hoses inside the building to attack any fire there, witnesses said.

There did not appear to be any injuries and witnesses said a family dog was removed safely.
