Fire officials said a blaze that scorched over eight acres of brush and forest last week was likely set. No buildings or private property were threatened.
Officials have no suspects.
One of the local fire towers also spotted smoke coming from the area. When firefighters arrived, they found three separate fires, each about an acre in size, burning along a path in the woods which stretch between the two schools. It took 20 firefighters over two hours to control the fire. Randolph and Avon assisted at the scene while Braintree covered the stations.
