The attack occurred shortly before midnight Thursday at a residence in the St. Thomas Square community, south of downtown Tulsa, Oklahoma, the Tulsa Police Department said in a statement released Friday.
"Officers learned the boys' father was upstairs sleeping when the 12-year-old daughter woke him up and told him that she had stabbed her 9-year-old brother," police said.

It was not clear if the girl, whose name was withheld because of her age, has a lawyer.

Children 12 and under cannot be detained, but state law provides exceptions in cases of serious charges, amounting to felonies, where the child poses a risk to the community or to himself.
Oklahoma law draws the line at age 13 by allowing a child that age or older to be prosecuted as an adult on felony murder charges.
The Tulsa Police Department's Children's Crisis Unit investigated the case.
