A Canadian citizen arrested near the St. Zacharie Port of Entry earlier this week and charged with entering the United States and hunting moose illegally has pleaded not guilty, officials said Friday. Simon Grenier, 51, is being held without bail in Piscataquis County Jail, a jail supervisor said. U.S. Border Patrol agents assigned to the Jackman Station, along with a Maine Warden Service game warden, arrested Grenier Tuesday on a federal charge of illegal entry to the United States, and on state charges of hunting moose during a closed season, hunting moose overlooking bait and hunting moose without a permit, according to the U.S.
