Several cars caught fire this morning in the vicinity of 270 Highland Ave and the incident is being investigated by the fire depaerment’s arson unit, according to Police Captain Paul Upton.

Two cars burned in the vicinity of 270 Highland Ave. with one suffering almost total damage, Upton said. Two more cars burned nearby on Aberdeen Road, he said. No injuries were reported.

A post on Davis Square LiveJournal described the scene: "Woke up at a little before 2 a.m. to smashing of windows and general mayhem, and looked out the window and saw flames reflected in the house across the street. Heard more explosions, and called 911, ran outside, and saw the cars on fire in the parking lot under the building overhang. Still more explosions as the firefighters worked to put out the fires. It looked as if some part of the building lobby may have caught fire, or it could have just been flaming debris obscured by smoke. There were reports of someone fleeing the scene, running down Highland towards Porter St., but other observers, noted he was just watching the fire, and bolted when the car started exploding."

Upton said the incident is being investigated by the Somerville Police Department and the Somerville Fire Department’s arson unit. No further information is available at this time.
