CHICO, Calif. -

Two Chico juveniles are in custody after police say they threatened another teenager with a weapon at Marsh Jr. High School.

Officers were called out just before 7 p.m. Wednesday night.  A boy was reportedly threatened by the suspect who waved a what he thought was gun while telling the victim he would kill him.

Officers later found the suspect with 3 other juveniles on Forest Avenue near Springfield drive.   They were carrying two knives and a screwdriver.

Police believe that the handle of the screwdriver may have been mistaken for the handle of a gun.   Two juveniles were arrested for possession of a knife on school grounds.
