A report of a natural gas smell led to the arrest Saturday afternoon of an Elliston man on a DUI charge, his sixth.

William Dean Boyle, 48, was arrested at about 1:12 p.m. after firefighters with the West Valley Volunteer Fire Department, responding to the report of the gas leak in the 4300 block of North Montana Avenue, reported a suspected drunk driver to Lewis and Clark County sheriff’s deputies, according to an affidavit in Justice Court.
