A California father has asked a judge for a restraining order against a nine-year-old boy who he says is bullying his son.

The student, who's in the fourth grade at Rolling Hills Elementary School in Fairfield, Calif., said he was punched in the face by another student at the school.

The boy's father, Stephen Feuder, said the bullying has been going on for about five months, and seeking a restraining order is his last resort.

"I've tried everything else, so why not try that," Feuder said.

Feuder said the school, citing privacy concerns, refused to give him any information about the alleged bully. So he turned to the court system instead.

"I'm glad I did it," Feuder said. "Not only for my son, but now for the rest of the children."

Feuder is not the first parent who has turned to the court system in hopes of trying to stop a bully.

Last year a Florida family got a restraining order against their daughter's bully, and in 2012 the mother of a Kentucky fourth grader did the same after the school refused to separate her daughter from a bully.
