Battle Creek Police are investigating after a mother called 911 when she discovered her daughter in her room with a butcher knife.

It happened Tuesday around 6:30 p.m.

WWMT reports that when police asked the girl about the knife, she admitted that she was attempting to kill her mother.

The girl faces possible charges of felony aggravated assault.
