A traffic violation stop Wednesday resulted in the arrest of a man against whom there was a failure-to-appear warrant and led to the confiscation of a weapon, a "large amount of U.S. currency’’ and a "stash of checks,’’ according to reports. A Covington Police officer was in the area of South Sterling Lakes Drive, reports said, when he saw a red SUV run a stop sign. When the officer pulled the car over, the driver, identified as Gian Windham, said he was picking up a friend and did not know there was a stop sign there.
