(Preble County, OH)--A local school resource officers remained held without bond Monday morning after having been accused of having a sexual relationship with a student at the school he was assigned to protect.  26-year-old Mason Williams is now on paid administrative leave with the Preble County Sheriff’s Department.  The alleged relationship was consensual and involved an 18-year-old student at National Trail.  Even though the student is of legal age, it’s still considered a crime due to Williams’ position of authority.  "When law enforcement investigates and arrests one of their own, it's imperative that we be transparent with what we learned and how we reponded," said Sheriff Mike Simpson.  The investigation has been turned over to Montgomery County.  Williams is being held without bond in the Butler County Jail.
