A Bossier City man has been arrested following a fight with his live-in girlfriend. Bossier Sheriff's deputies say 66-year-old Louis Taylor, who has been living with his girlfriend for three years, got into a verbal argument with her, and told her to leave the house. When she turned around, Taylor began pushing her out of the doorway. He reportedly pushed her hard enough in the back that she had to brace herself against Taylor's vehicle, causing a dent in the quarter panel. The girlfriend says he then went back inside, grabbed a kitchen knife and told her to leave...or he would kill her -- which he denies. Taylor was arrested for domestic abuse battery and aggravated assault.
