A bomb threat in Ware over the weekend turned out to be a hoax.  Similar threats have occurred in Barre, West Brookfield, Warren and Milton.  Police say they're questioning a suspect but haven't made any arrests.  In the Ware case, a man called police to report a bomb across the street from a National Guard post.  More than 100 police and firefighters responded, including the State Police bomb squad and haz mat teams.  They found no explosives during their 12 hour search.
