The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Boston Field Division, announced Wednesday that they are offering $5,000 added to the existing $5,000 reward set up by an insurance organization for the arrest of a suspect or suspects responsible for three suspicious Jamaica Plain fires.

According to the ATF, a Feb. 7 fire at 22 Sigourney Street has been ruled an arson. Investigators are reviewing surveillance video obtained from that incident. They are trying to piece together clues that could indicate that fire is related to a Jan. 6 fire on South Street and a Jan. 28 fire on School Street. All three fires were ruled arsons and have “investigative similarities.’

Anyone with information about any of the arson incidents or the identity of the suspect is asked to contact the Arson Hotline at 617 343-3324. Anonymous tips can be placed at 1 800-494-TIPS or text the word “TIP” to CRIME (27463).
