WINDHAM (AP) – The state fire marshal is investigating an early morning blaze that damaged three storage buildings at an industrial complex in Windham.

Officials say they found three buildings on fire when they arrived at the site on Cherry Lane shortly before 3 a.m. Monday.

Two of the buildings were used to store boats. The third building, which sustained the heaviest damage, was rented by a portable toilet company.

Nobody was hurt in the fire, but it was difficult to put out because there are no hydrants in the area.
