Kern County sheriff's deputies responding to a 911 hangup in Rosamond early Tuesday confronted a 9-year-old boy armed with kitchen knives in his home.

The juvenile threatened to stab his mother, ran with knives raised in a threatening manner and said it was "time to die," a sheriff's department news release said. Deputies used pepper spray on him.

The juvenile dropped the knives, covered his face and fell to the ground as the spray took effect, the news release said. They took the boy to a medical facility in Bakersfield for a 72-hour evaluation.
