PORTLAND, Maine — A 53-year-old New Hampshire man was convicted Tuesday of assault on a Coast Guard officer.

Scott Jellison of Derry, N.H., was found guilty by a jury after a trial in U.S. District Court in Portland, U.S. Attorney Thomas E. Delahanty II announced Wednesday.

Court records show that in November 2010, Jellison was operating his fishing vessel off the coast of southern Maine when Coast Guard officers encountered him in an area that had been closed to civilian boating due to an ongoing U.S. Navy SEALS training exercise.

With Jellison’s permission, Coast Guard officers boarded the vessel. Although Jellison claimed that his navigation equipment was not working, an officer found all of the equipment to be functional.

The officers concluded that Jellison was intoxicated and incapable of operating his vessel out of the training zone and back to shore so the officers moved the vessel out of the training zone.

While heading back to shore, Jellison assaulted one of the Coast Guard officers and then resisted attempts to subdue him.

A date for his sentencing hearing has yet to be set.
