Members of the state Fire Marshal’s Office charged an Acton man with setting a string of fires near his home last month, arresting him after his treatment at a local psychiatric facility.

Members of the state Fire Marshal’s Office charged John Hogan III, 56, with six counts of arson stemming from fires set on April 27, according to the Department of Public Safety.

The fires destroyed two houses, a pontoon boat, an SUV and a shed. A third house was damaged.

The first fire was reported shortly after 10 p.m. Wednesday and it was followed by fires that burned the boat, a car and three homes nearby.

About 75 firefighters from 10 departments in Maine and New Hampshire responded.

Hogan was arrested at noon today in Westbrook upon his release from Spring Harbor Hospital and was taken to York County Jail in Alfred. He could make his first court appearance Friday.
