Flames erupted from the hood of a car in Acton, Massachusetts, Monday morning, leaving the front of the car completely charred.
The culprit may have been a squirrel's nest, local police said in a tweet.
An early investigation of the fire, which erupted on Carriage Drive Monday morning and was put out by local firefighters, "indicates it was possibly a squirrel's nest" that caused it, police said.

Photos shared by Acton police showed the intensity of the fire, with flames shooting up from the fully engulfed hood as a firefighter sprayed the car down. The flames melted some of the metal and appeared to eat through much of the engine.
Squirrels and other rodents are known to be a hazard for cars, where they sometimes build nests, especially in winter.
