A 14-year-old ninth grader has admitted threatening to kill people at random at Council Rock South High School last month.

The Bucks County District Attorney’s office says the boy, whose name has not been released, pleaded no contest to charges of terroristic threats and possession of a firearm by a minor and the juvenile court adjudicated him delinquent.

Knives and swords and two working pistols were found in the bedroom of his Richboro home, and he has been held at the Bucks County Youth Detention Center since his arrest on December 20.
