The state Fire Marshal’s Office has charged a Thorndike man with arson following a fire Saturday that heavily damaged his house.

According to a press release from Steve McCausland, spokesman for the Department of Public Safety, fire investigators working with the Waldo County Sheriff’s Office charged Randy Tremaine, 42, with arson, domestic violence assault and violating conditions of release on Monday.

Tremaine reportedly threatened firefighters who responded to the blaze, according to the release. Firefighters subdued him, tied him up and waited for deputies to arrive while they put out the fire.

Tremaine was taken to a Bangor hospital for self inflicted injuries and released late Monday morning, the release said, and he is now being held at the Waldo County Jail.

The fire followed an altercation with Tremaine’s ex-girlfriend, who had gone to the house to retrieve her belongings. The fire destroyed a shed on Tremaine’s property and badly damaged his house, the release said.
