As worries of arson persist in Somerville, firefighters say a two-alarm blaze in the city Thursday night that displaced four people does not appear to be suspicious.
The exact cause of the fire at 27 Dickinson Street is still under investigation, but firefighters and police are looking at several possible accidental causes, according to a joint release from the state Fire Marshal and the Somerville fire and police departments.
Firefighters responded to the 2 ½ story home near Inman Square for a fire at 7:42 p.m. and Somerville Fire Chief Kevin Kelleher said it took about 45 minutes to knock down the flames.
No one was home at the time the fire broke out, and Kelleher said no firefighters were injured while extinguishing the blaze.
Kelleher said the fire appears to have started on the second floor and when firefighters arrived they found heavy fire on the second and third floor, Kelleher said. He said the house suffered extensive damage.
The blaze comes as residents in the city are on edge about a rash of arsons and suspected arsons over the summer. Kelleher said that since June the city has had four fires that investigators believe were intentionally set and another seven that are still under investigation.
