Officials are investigating a series of arsons and acts of vandalism on Alexander Avenue in Medford.

The first arson occurred on the evening of Feb. 25 near 85 Alexandre Ave., when a 911 call reported fire and smoke coming from the address, according to a statement from the Medford Police Department. Investigators collected evidence found at the scene for further investigation and determined the fire was intentionally set, police said.

On March 3, at about 11:25 p.m. a similar incident occurred in the area of 96 Alexander Ave. There have been several acts of vandalism in the past few months in the same area and investigators believe there may be a connection between the vandalism and the fires, according to the statement.

The investigation is run by the State Fire Marshal’s Office, the Medford Police Department and the Medford Fire Department.

Investigators ask anyone with information about these crimes to contact the Medford Police Department Investigative Services Unit (781 -391-6765) or the statewide, toll-free Arson Hotline at 1-800-682-9229. All calls are confidential.

The Arson Watch Reward Program, funded by the property and casualty insurance companies of Massachusetts, is offering a reward of up to $5,000 for information that helps to solve the case.

In an e-mail to Medford Patch, Lt. Paul Covino wrote that the Medford Police Department has no further comment on this situation.
