Police say a man from Gonzales is under arrest after he allegedly drove to Louisiana State Police Troop A headquarters drunk. Investigators say it happened around 3:00am Saturday when 31-year-old Patrick Ruffner called to report he'd been involved in a hit and run on I-10 near Seigen Lane in Baton Rouge. Police say they advised the man to come file a report. It was at that time troopers suspected he was impaired. They say he was above the legal limit for alcohol, so they arrested him. Ruffner was booked on 1st offense DWI.
