A truck hit a building on Saturday morning in Bethel and caused a natural gas leak.  The pick up truck with landscaping trailer was located inside a Grassy Plain Street building shortly after 11am.  The accident caused severe structural damage and a severed natural gas meter going to the unit.  Firefighters set up a protective ground monitor, keeping a constant flow of water on the gas leak. After the gas was shut off, the Bethel Emergency Management & Fire Marshal and Town Building Department responded to the scene to begin investigating.  Bethel Police and Danbury Fire Department  were also on scene assisting while West Redding Volunteer Fire Department provided station coverage.  The driver was uninjured.
