Dad Gets Restraining Order Against 4th-Grade Bully

A Southern California dad has taken out a restraining order against a classmate of his fourth-grade son who he says threatened his boy with a knife.

A judge has granted a temporary order requiring the classmate to stay at least 20 feet away from Robert Casteel's 10-year-old son, Christopher.

"My son was terrified," Casteel said. "I kept him home for five days until I got the restraining order."
