An Oklahoma City woman has been arrested, after her 7-year-old grandchild told officials she had been abused.

FOX25 News out of OKC states 49-year-old Geneva Robinson brought her grandchild into an area hospital.  Robinson is said to have told an unidentified person she "could not control her anymore."

Doctors examined the little girl and immediately called DHS.

Police say the girl told officials Robinson liked to dress up as a witch, and would wear a green mask.  She would even go by the name "Nelda."

While dressed up, Robinson is accused of abusing the child.  She's said to have used a dog leash to hang the girl up by her arms in the garage.

Robinson had been living with multiple children inside the home.

Police say they're also investigating if Robinson held a "wand knife" up to the their necks.

Robinson was taken to the Oklahoma County Jail.
