An 18-year-old Star Wars fan has been arrested in Helena, Montana after reportedly threatening a friend's life for spoiling plot secrets for The Force Awakens on Facebook. Arthur Charles Roy allegedly sent the pal a photo of himself brandishing a gun last Thursday (17Dec15), when previews of the highly-anticipated movie opened in the U.S., and reportedly vowed to go to his school and gun him down. He was arrested on Friday (18Dec15) after the school was placed on lockdown.
