The fire that destroyed five buildings in downtown Milo early Sunday morning was arson, the State Fire Marshal's Office said today.

Investigators said the fire started underneath a rear stairway on the outside of the building that housed Hobknobbers Pub. The fire spread to the roof of that building and then jumped to four other buildings along Main Street.

Investigators said the pub had been broken into prior to the fire.

Fire Marshal investigators say they questioned a "person of interest," but they have yet to make any arrests.
