New Port Richey, Florida -- Pasco deputies say a man attacked his girlfriend after she walked in on him with another woman.
The girlfriend told deputies she caught 29-year-old Adam St. Valle having sex with a woman she only knows as "Danielle" on Friday.
St. Valle allegedly responded by brutally attacking his girlfriend, striking her in the face and knocking out several teeth. The girlfriend claims he also held a knife to her throat.
St. Valle claimed the girlfriend injured his penis during the fight, but deputies saw no sign of any injuries. The girlfriend, however, had several fresh and bleeding abrasions on her face and neck.
Deputies arrested St. Valle and charged him with one count aggravated domestic battery.
