Westport Police have arrested a Danbury man twice in one week on drunk driving charges. Police stopped a car last Tuesday evening after the driver was seen swerving. 50-year old Bradford Brown failed field sobriety tests. Last Friday, Brown was stopped for driving a car he took from a Westport resident without permission. He refused to take field sobriety tests. Brown is due in court today on the first DUI and next week on the second DUI.
