NEW PORT RICHEY — The fight started with an argument at a red light.
Both women pulled over, a Pasco Sheriff's report states, and Ariana Alexandra Gaton, 19, got out of her car. She went to the other woman's open driver-side window and yelled, beat the woman's car and chucked a CD inside. Out of fear, the report states, the other woman hit Gaton in the face.
The woman got out of her car and they grappled. The other woman would later tell deputies she didn't know she'd been stabbed until Gaton showed her the knife.
The woman, whose name was not released, suffered multiple stab wounds to her abdomen and left shoulder, reports state.
When deputies asked Gaton about it, she told them she had a knife she keeps by her driver's seat. She said she used it when the other woman got out of her car and started hitting her.
The other woman was taken to Regional Medical Center Bayonet Point.
Deputies arrested Gaton, of 29443 Allegro Drive in Wesley Chapel, on a charge of aggravated battery with a deadly weapon. She has since been released on $10,000 bail.
