GORHAM — The town is offering a reward of up to $10,000 to help solve a string of arsons.

The Town Council yesterday voted unanimously to offer the reward for information leading to the arrest and conviction of those responsible for the fires.

“I’m not aware of the town offering a reward before. I’m not aware of having a similar situation before either,” said Town Manager David Cole, who has worked for Gorham since 1994.

A series of six suspicous fires began on March 27. The most recent arson targeted an unoccupied house on Route 237 early Wednesday morning.  Five of the six fires have been confirmed as arson and the remaining one appears to be as well, but investigators are awaiting lab results to confirm.
