A house fire in Holyoke earlier this week is being ruled an arson.
Authorities say a fire at a home on Pine Street Tuesday morning was intentionally set.
Six people were displaced and a firefighter was injured.
The Fire Marshal's Office is asking residents to share any information they might have with the Arson Watch Reward Program at 1-800-682-9229.
The Arson Watch Reward Program is coordinated by the Massachusetts Property Insurance Underwriting Association and offers rewards of up to $5,000 for information that solves, detects, or prevents arson crimes.
The investigation is ongoing.
