NEW GLOUCESTER — The state Fire Marshal’s Office is investigating a suspicious motor vehicle fire at a business on Route 100 Tuesday night, said New Gloucester Fire Chief Gary Sacco.

No one was injured in the fire at Portland Insulation’s parking area at 162 Lewiston Road. A pickup truck was destroyed and a parking structure and nearby vehicle were damaged, Sacco said.

The fire was reported at about 9:30 p.m. as a structure fire. Firefighters found the pickup in flames and fire spreading to the roof that covered several commercial vehicles.

Except for the loss of the pickup, the fire did minimal damage to the property and the business is operating as usual today, Sacco said.

Sacco would not discuss the cause of the fire other than to say it is suspicious and being investigated.
