An Elm Grove teenager has been arrested following a dispute with his girlfriend over the weekend. Bossier sheriff's deputies say 18-year-old Clarence McCoy slapped and punched his girlfriend in the face, causing her to drop their one-year-old daughter. A male came in and tried to stop McCoy, but McCoy reportedly hit him in the face several times. Deputies say the girlfriend had visible swelling to the left side of her face and a visible handprint on the right side of her face. The male who tried to intervene had a bloody nose and swollen forehead. McCoy was arrested at a Bossier City business and booked into Bossier Max on two counts of simple battery and one count of cruelty to a juvenile. His bond's been set at $16,000.
