News outlets report authorities say 57-year-old Tracy Hollifield, who also goes by Tracy Fazekas, was arrested in Knoxville and charged with aggravated assault and public intoxication.
Knoxville police say they were called to fight Saturday evening and found two adults and two 12-year-old children with lacerations and other injuries that aren't considered life-threatening.
Police say Hollifield is accused of attacking one of the children first. Court records say the child's mother stepped in and Hollifield pulled a knife, so both children and another woman stepped in to help.
Police say Hollifield ran when she heard sirens but was located a short time later.
It wasn't immediately clear whether she has an attorney.
