PHOENIX -- A woman has been charged with child abuse, accused of spanking her two grandchildren with a belt in front of the children's mother, who also has been arrested.
Stacy Hamby, 43, and Laura Hamby, 24, were being held on two counts of felony child abuse.
Their bond was set Monday at $25,000 apiece at their initial court appearance. Neither woman has a lawyer yet.
Police said they were called by authorities at the girls' elementary school after a nurse found bruises on the children's buttocks and thighs Wednesday.
The girls, 6 and 8, said they were punished for not going to sleep at their apartment.
Stacy Hamby reportedly told police she was upset at the girls' behavior and was under some stress.
